&lt;h4&gt;Objective&lt;/h4&gt;
&lt;p&gt; Authorship confers credit and has important academic, social, and financial implications.&lt;sup&gt;1&lt;/sup&gt; Although certain journals, such as &lt;i&gt;JAMA&lt;/i&gt;, enforce strict authorship policies, the recognition of equal contributions by 2 or more co–first and/or co–corresponding authors is increasingly common in biomedical publishing.&lt;sup&gt;2,3&lt;/sup&gt; Both the &lt;i&gt;Chinese Medical Journal&lt;/i&gt; (&lt;i&gt;CMJ&lt;/i&gt;) and &lt;i&gt;JAMA&lt;/i&gt; are peer-reviewed general medical journals covering all major medical disciplines. This study evaluated the prevalence of co–first and co–corresponding authors in &lt;i&gt;CMJ&lt;/i&gt; and &lt;i&gt;JAMA&lt;/i&gt;.&lt;/p&gt;
&lt;h4&gt;Design&lt;/h4&gt;
&lt;p&gt; From January 1 to January 21, 2025, we examined all articles published in &lt;i&gt;CMJ&lt;/i&gt; and &lt;i&gt;JAMA&lt;/i&gt; in 2024, excluding News, Editors’ Notes, Corrigendum/Correction, Humanities, and miscellaneous sections, to assess the frequency of co–first and co–corresponding authorship. Other characteristics examined included article type, subject, and geographic location of corresponding authors. A multivariate logistic regression model was used to identify characteristics associated with co–first or co–corresponding authors.&lt;/p&gt;
&lt;h4&gt;Results&lt;/h4&gt;
&lt;p&gt; Of the 473 articles published in &lt;i&gt;CMJ&lt;/i&gt; in 2024, 233 (49.3%) included co–first authors and 180 (38.1%) included co–corresponding authors. &lt;i&gt;JAMA&lt;/i&gt; published 1011 articles in 2024; among them, 42 (4.2%) had co–first authors and 18 (1.8%) had co–corresponding authors. Original articles most frequently featured co–first and co–corresponding authors in both journals (&lt;b&gt;Table 25-0882&lt;/b&gt;). In &lt;i&gt;CMJ&lt;/i&gt;, gastroenterology was the most frequent subject associated with both forms of shared authorship. In &lt;i&gt;JAMA&lt;/i&gt;, public health had the highest number of co–first authors, while cardiology had the most co–first and co–corresponding authors. In &lt;i&gt;CMJ&lt;/i&gt;, most corresponding authors of articles with co–first or co–corresponding authorship were based in China. Logistic regression analysis revealed that article type, subject, and corresponding author’s geographic location were not significantly associated with shared authorship status in &lt;i&gt;CMJ&lt;/i&gt;. By contrast, in &lt;i&gt;JAMA&lt;/i&gt;, article type was significantly associated with both co–first and co–corresponding authorship, and corresponding author’s geographic location was significantly associated with co–corresponding authorship. &lt;i&gt;CMJ&lt;/i&gt; showed a higher prevalence of co–first (χ² = 431.3; &lt;i&gt;P&lt;/i&gt; &amp;lt;.001) and co–corresponding (χ² = 363.6; &lt;i&gt;P&lt;/i&gt; &amp;lt; .001) authorship than &lt;i&gt;JAMA&lt;/i&gt;.&lt;/p&gt;

&lt;h4&gt;Conclusions&lt;/h4&gt;
&lt;p&gt; This study demonstrates a significant difference in the prevalence of co–first and co–corresponding authorship between &lt;i&gt;CMJ&lt;/i&gt; and &lt;i&gt;JAMA&lt;/i&gt;.&lt;i&gt; &lt;/i&gt;China and the United States are among the leading countries in scientific output. Compared with US-based authors, Chinese authors were more likely to designate co–first and co–corresponding authors. This trend may reflect the academic, social, and economic significance of shared authorship roles within the Chinese research evaluation system. While journals such as &lt;i&gt;JAMA&lt;/i&gt; impose restrictions on shared authorship, increasing multidisciplinary collaborations and the rise of team science have led others, such as &lt;i&gt;CMJ&lt;/i&gt;, to adopt more flexible policies. Establishing a standardized framework for managing co–first and co–corresponding authorship is needed.&lt;/p&gt;

<h4>Objective</h4>
<p> The International Committee of Medical Journal Editors (ICMJE) authorship criteria ensure appropriate credit for significant research contributions, while the Contributor Role Taxonomy (CRediT) framework offers a detailed account of individual scholarly contributions. Despite these frameworks, honorary authorship remains widespread in health sciences,<sup>1</sup> and surveys from Africa have documented its prevalence and the difficulty of applying authorship standards.<sup>2</sup> This study evaluated the fulfillment of ICMJE authorship criteria and CRediT contributions in manuscripts submitted between 2017 and 2023.</p>
<h4>Design</h4>
<p> This retrospective study analyzed the fulfillment of ICMJE authorship criteria and author-reported CRediT contributor roles for manuscripts submitted to <i>Annals of African Surgery</i>, a journal that endorses the ICMJE authorship criteria, between 2017 and 2023. The evaluated ICMJE criteria included criteria 1 (intellectual input) and 2 (manuscript drafting or critical revision) because these are the only author-level items captured as discrete checkboxes in the submission system. Criteria 3 and 4 were not assessed because they are captured as a collective attestation in a signed mandatory licence agreement required at submission. Data were retrieved from the journal’s online manuscript management system. CRediT roles were scored using a weighted system: 3 points for lead, 2 for equal, and 1 for supporting contributions across 14 roles, with a maximum possible score of 42 converted to a percentage. Descriptive statistics summarized ICMJE compliance and CRediT role distribution.</p>
<h4>Results</h4>
<p> A total of 1619 authors and 448 manuscripts with complete authorship data were evaluated. Among the authors, 1027 (63.4%) met both ICMJE criteria 1 and 2, 460 (28.4%) met only 1 criterion, and 132 (8.2%) met none. Of the 1619 authors, 709 (43.8%) were supervisors; among these supervisor authors, 523 (73.8%) met both criteria, 124 (17.5%) met only 1 criterion, and 62 (8.7%) failed to meet any. A total of 9610 CRediT contributor roles were analyzed. On weighted CRediT scores, 275 (17%) authors had a contribution score above 50%, while 971 (60%) scored 25% or less. Among 709 supervisors, 241 (34%) had scores above 50% and 269 (38%) scored 25% or less. Funding acquisition was credited to 296 authors (18.3%). Among the supervisor authors, 248 (35.0%) reported funding acquisition, accounting for 83.8% of all authors who claimed that role.</p>
<h4>Conclusions</h4>
<p> Using ICMJE criteria, supervisor involvement appeared to be limited, suggesting a high prevalence of guest authorship. However, weighted CRediT scores indicated that supervisors often contributed significantly, more so than other coauthors, highlighting a disconnect between traditional authorship criteria and actual contributions. Although limited to 1 journal, this study demonstrates the value of integrating authorship criteria audits with CRediT data, while noting the potential for checkbox behavior by submitting authors who may not grasp the significance of their declarations.</p>

Authorship and Contributorship Criteria and Practices at the Annals of African Surgery

<p>Mohammad Hosseini,<sup>1</sup> Sofie Elaine Adams,<sup>2</sup> Yensi Flores,<sup>3</sup> Kathleen Hall Jamieson,<sup>2</sup> Joerg Heber,<sup>4</sup> Jennifer Heimberg,<sup>5</sup><span lang="ar-SA"> Véronique Kiermer,</span><sup>6</sup> Arthur Lupia,<sup>7</sup> Ana Marušić,<sup>8</sup> Beau Nielsen,<sup>5</sup> Magdalena Skipper,<sup>9</sup> Geeta Swamy,<sup>10</sup> Susan Wolf<sup>11</sup></p>
<h4>Objective </h4>
<p>Although authorship is a cornerstone of the reward system of science, it is often fraught with disagreements and questionable practices.<sup>1</sup> A working group (including authors of this abstract and additional experts) was convened in January 2024 by the National Academy of Sciences (NAS) Strategic Council on Research Excellence, Integrity, and Trust to examine the impact of previous recommendations on institutional and journal authorship policies.<sup>1,2</sup></p>
<h4>Design </h4>
<p>Our analysis consisted of 2 parts completed in 2024 and 2025. First, we examined authorship policies of the AAAS, AGU, APS, <i>BMJ</i>, <i>Cell</i>, ICMJE, IEEE, JACS, <i>Nature</i>, <i>NEJM</i>, PLOS, <i>PNAS</i>, and SAGE (represented in the group members who authored the NAS 2018 recommendation<sup>2</sup>) to examine the extent to which they had adapted policies. This review captured trends regarding authorship guidelines, use of ORCIDs, and the CRediT taxonomy. Second, we searched the websites of all R1 (very high research activity) institutions (search terms <i>authorship</i>, <i>authorship guidelines</i>, <i>research guidelines</i>, and <i>research integrity</i>) in the US (n = 146) to determine whether credit and accountability or responsibility were mentioned in authorship guidelines and, if so, whether they were cast as related concepts. We then checked whether guidelines included links to external instructions (eg, ICMJE) and encouraged meetings to discuss authorship. Both phases were followed by brainstorming sessions among working group members.</p>
<h4>Results </h4>
<p>Of the examined journal groups, 5 adopted ICMJE guidelines, 2 referenced the NAS 2018 recommendations, and others had different recommendations. Seven groups recommended using the CRediT taxonomy, but only 3 required ORCIDs for all authors. Of the 146 R1 institutions, 59 included a credit-accountability link in their guidelines, but in only 38 cases did the credit-accountability link appear at the top of the guideline. Guidelines of 60 institutions suggested authors meet proactively to discuss authorship.</p>
<h4>Conclusions </h4>
<p>Anchoring authorship in credit (give credit where it is due) and accountability (authors are accountable for the integrity of the work) principles<sup>2</sup> readily explains why questionable practices (eg, gifts, ghost writing, and coercive authorship) are problematic and helps determine when authorship credit is warranted. Providing a clear description of contributions reinforces the application of these principles and fosters transparency as an important complementary principle.<sup>3</sup> While journals should choose authorship guidelines that suit their context, encouraging the use of ORCID and taxonomies such as CRediT are beneficial. Aligning institutional guidelines with the credit-accountability framework offers an opportunity to improve authorship practices. We plan to engage with institutional leaders to explore ways to support these improvements (eg, by offering educational materials or courses, providing mechanisms to resolve conflicts, and offering a safe environment for discussing authorship).</p>

Integration of Credit and Accountability Principles in Authorship Policies of Science Journals and Research Institutions

<p>Stephan D. Fihn,<sup>1,3</sup> Roy H. Perlis,<sup>2,3</sup> Jacob Kendall-Taylor,<sup>3</sup> Annette Flanagin<sup>3</sup></p>
<h4>Objective</h4>
<p> The major challenges for editors of journals include attracting submissions of high-quality manuscripts and recruiting reviewers.<sup>1</sup> In light of a dearth of relevant research, we sought to ascertain the association between publishing manuscripts as an author and participation in peer review for the same journal.</p>
<h4>Design</h4>
<p> We conducted a cross-sectional study using data extracted about authors and reviewers for <i>JAMA Network Open</i>, a high-volume open access general medical journal, for the years 2019 to 2023, including number of articles submitted and published as first or corresponding author during this period, numbers of requests to review and response (submitted, declined, no response), and quality of review submitted as determined by reviewing editor on a 5-point Likert scale (excellent = 1 to poor = 5). Data were analyzed using R 4.4.2.</p>
<h4>Results</h4>
<p> Among 38,683 invited reviewers, 30,082 (77.8%) submitted no manuscripts; 4014 (10.6%) submitted ≥1 article as first or corresponding author but had no published articles; and 4497 (11.6%) submitted ≥1 article as first or corresponding author and had ≥1 publication. <b>Table 25-1097</b> summarizes review requests to these individuals and compares their rates of accepting reviews and ratings among those who returned reviews. The mean (SD) number of invitations was greatest among published reviewers (5.1 [9.5]), followed by those with submissions but no publications (3.4 [6.1]), and then individuals with no submissions (2.7 [5.9]) (<i>P</i> &lt; .007 by analysis of variance). Reviewers with publications were significantly more likely to accept invitations and significantly less likely to ignore invitations compared with the other 2 groups (<i>P</i> &lt; .01 by analysis of variance and post hoc pairwise test). The absolute difference in proportion of accepted invitations was 26.2% (95% CI, 24.8%-27.6%; <i>P</i> &lt; .001) between published and never-submitted reviewers and 11.6% (95% CI, 9.7%-13.5%; <i>P</i> &lt; .001) between published and nonpublished submitters. Among those who returned reviews, quality (mean rating) was significantly higher among reviewers with publications (absolute difference from nonsubmitters: 0.25; 95% CI, −0.29 to −0.20; <i>P</i> &lt; .001). Differences between submitters without publications (mean difference: 0.03) and never-submitters (mean difference: 2.5%) were minimal for both rating metrics (<i>P</i> &gt; .50).</p>
<a href="/wp-content/uploads/2025_conference/tables/prc25-1097t1.png"> <img loading="lazy" src="/wp-content/uploads/2025_conference/tables/prc25-1097t1.png"> </a>
<h4>Conclusions </h4>
<p>Authors who published in <i>JAMA Network Open </i>were significantly more likely to accept an invitation to review even though they received nearly twice as many requests as those who did not publish. Moreover, the quality of their reviews was significantly greater. Individuals who submitted manuscripts but did not publish were intermediate between these 2 groups in terms of accepting invitations to reviews and quality of reviews. These results suggest that investigators may be willing to commit more of their academic effort to journals that publish their work. Limitations of this analysis include the inability to determine the relative timing of publication versus review; restriction of the analysis to a single high-volume journal; exclusion of co-authors; and limitation to a 4-year time frame.</p>

Authors Who Publish in a Journal and Likelihood to Serve as Reviewers

<p>Sidney Xiang,<sup>1</sup> Daniel M. Romero,<sup>1,2,3</sup> Misha Teplitskiy<sup>1</sup></p>
<h4>Objective</h4>
<p> Prior literature on interdisciplinary research evaluation does not include prepublication manuscripts or account for differential evaluation over multiple dimensions of interdisciplinarity. Based on management science literature, we introduce 2 novel dimensions: topic interdisciplinarity, which may incur evaluation penalties by cutting across disciplinary standards and threatening symbolic boundaries, and knowledge-base interdisciplinarity, which may incur benefits by combining larger pools of nonredundant information. Evaluations may also depend on how these dimensions align with each other and the audience. Our study tested these hypotheses using a large-scale dataset of journal submissions.</p>
<h4>Design</h4>
<p> We performed a case-control study using administrative data from the Institute of Physics Publishing, a major STEM publisher. The data included 128,950 manuscripts (accepted and rejected) submitted to 62 physical science journals from 2018 to 2022. We calculated topic interdisciplinarity with concept tags of the manuscript’s associated OpenAlex record<sup>1</sup> and knowledge-base interdisciplinarity with concept tags of the manuscript’s references. For each type, we quantified interdisciplinarity using the integration index,<sup>2</sup> ranging from 0 to 1. Logistic regression was used to model the relationship between both types of interdisciplinarity and 2 evaluation outcomes: final decision and review positivity, controlling for journal, manuscript type, year, number of authors, number of authors’ prior citations, number of authors’ prior publications, and number of references. We retained observations with both interdisciplinarities and all covariates.</p>
<h4>Results</h4>
<p> The marginal effect of a 1-SD increase in knowledge-base interdisciplinarity was a 0.9 (0.7) percentage point higher acceptance (positive review) probability, while a 1-SD increase in topic interdisciplinarity corresponded to a 1.2 (0.4) percentage point lower acceptance (positive review) probability. Interactions revealed that high knowledge-base interdisciplinarity attenuated the negative relationship between topic interdisciplinarity and acceptance. We did not see a symmetric effect when high knowledge-base interdisciplinarity was accompanied by high topic interdisciplinarity. When disaggregating model results by journal interdisciplinarity according to the publisher’s 2022 product catalogue,<sup>3</sup> journals categorized by the publisher as interdisciplinary or multisubject had positive associations between both types of interdisciplinarity and evaluation outcomes, whereas monodisciplinary journals had negative associations. Our results were robust to the inclusion and transformation of manuscript and team covariates.</p>

<h4>Conclusions</h4>
<p> Our findings indicate that different dimensions of interdisciplinarity have different relationships to evaluation and that, for successful publication, authors must attend to alignment between types of interdisciplinarity within the manuscript and between the manuscript and journal audience. Limitations include the scope of journals in our dataset (STEM only) and the reliance on matching submissions to OpenAlex records.</p>

Topic and Knowledge-base Interdisciplinarity in Manuscripts Submitted to Physical Science Journals vs Editorial Decision and Reviewer Positivity

<p>Neil Millar,<sup>1</sup> Brian Budgell<sup>2</sup></p>
<h4>Objective</h4>
<p> Promotional language (hereafter, <i>hype</i>) in scientific writing has increased significantly over the past 40 years.<sup>1</sup> Analyses of grant proposals have found the incidence of hype to be positively associated with funding success<sup>2</sup>; however, evidence of causality is still lacking. Furthermore, an underpowered pilot study suggested that hype may bias clinicians’ perceptions and evaluations of evidence.<sup>3</sup> This study tested the hypothesis that students’ appraisal of biomedical research abstracts is influenced by hype.</p>
<h4>Design</h4>
<p> A double-blind randomized controlled trial was conducted to assess readers’ evaluation of hyped vs nonhyped abstracts. Four structured abstracts were selected from leading spinal care journals, controlling for length and absence of hype. Hyped abstracts were modified to include 6 common hype terms, such as “carefully designed” to highlight methodological rigor, “this is the first study to” to emphasize novelty, “convincing evidence” to amplify results, and “conducted by an experienced radiologist” to emphasize researcher competence. Inclusion criteria were that participants were second-year or higher chiropractic students recruited from institutions in the UK, US, and Canada. A blinded researcher randomly selected folders for students to evaluate. Participants rated abstracts on a 10-point scale, using 4 criteria: implementation likelihood, rigor, novelty, and researcher competence. A linear mixed-effects model was used to assess whether evaluations were influenced by hype, accounting for variability across participants and abstracts.</p>
<h4>Results</h4>
<p> This ongoing study began on April 2, 2024. As of January 2025, 36 students at 3 institutions had completed the rating task. Mixed-effects modeling, including interactions between condition and criterion, showed no significant differences between hyped and original abstracts across all evaluation criteria (estimate, 0.067; <i>P</i> &gt; .05) (<b>Figure 25-0927</b>). While novelty received consistently lower ratings (estimate, −1.479; <i>P</i> &lt; .001), the influence of hype did not vary significantly by criterion, as interaction terms were nonsignificant (eg, condition × novelty interaction [estimate, 0.517; <i>P</i> &gt; .05]), indicating minimal measurable effect of promotional language.</p>

<h4>Conclusions </h4>
<p>Within this experimental paradigm, hype did not appear to bias readers’ evaluation of the scientific merit of the literature. These findings are discussed in relation to evidence-based medicine and bias on the part of researchers, reviewers, editors, and other stakeholders. Limitations of the study include the small sample size reported to date and restriction of the experimental texts to abstracts.</p>

The Influence of Promotional Language on Evaluations of Biomedical Literature: A Randomized Controlled Trial

<p>Vincent Yuan,<sup>1</sup> Aidan Christopher Tan<sup>2</sup> </p>
<h4>Objective </h4>
<p>Our study aimed to determine the prevalence, types, and facilitators of “spin” and other selective reporting practices in recently published medical artificial intelligence (AI) research.</p>
<h4>Design </h4>
<p>This was a cross-sectional meta-research study of interventional and observational studies related to medical AI. Medical AI was defined as computational models (eg, machine learning, deep learning, natural language processing) that amplify or augment health care–related tasks (eg, diagnosis, prognosis, risk stratification).<sup>1</sup> Studies were identified by searching MEDLINE, Embase, and the Cochrane Library. Studies were included if they were observational or interventional studies related to medical AI published in 2023, English-language, and full text. Spin was defined as the distortion of findings to present the performance of a medical AI tool as more beneficial than it appears. Examples of spin include misrepresentation or omission of significant or nonsignificant results and selective focus on abstract conclusions. Other study characteristics investigated included the journal, academic qualifications of first authors, funding, and competing interests. The features of spin were derived from coding manuals of Boutron et al<sup>2</sup> and Andaur Navarro et al.<sup>3</sup> Spin was categorized as either misleading interpretation, referring to an overemphasis of results, or misleading transportability, referring to an exaggeration of a model’s clinical applicability. Instances of spin were abstracted by manually reviewing the Results and Discussion sections of abstracts and body and extracting the data into a prepiloted data collection form. This form was modified from SPIN-Prediction Models to exclude or include certain indicators, with the addition of custom items based on previous spin studies. Data were collected by 1 reviewer, and a second reviewer independently recollected the data in instances of uncertainty.</p>
<h4>Results </h4>
<p>A total of 423 studies were included (<b>Figure 25-0950</b>). Slightly more than one-third (35% [n = 149]) of studies described AI as superior to the comparator. Nine percent of studies (n = 38) contained leading words in the title, and more than half (56% [n = 236]) selectively focused abstract conclusions on significant results. In almost half (48% [n = 203]) of study abstracts, qualifiers (eg, <i>might</i>, <i>very</i>) were present to subtly suggest stronger findings than likely warranted. The majority of studies (71% [n = 300]) contained strong statements (eg, <i>clearly shows</i>) in the body to emphasise the AI model’s performance, accuracy, or effectiveness. Twenty-four percent (n = 101) of studies made recommendations for clinical practice in the body without external validation in the same study.</p>

<h4>Conclusions </h4>
<p>Our findings suggest that selective reporting practices, including spin, are prevalent in medical AI research. These practices can misinform readers of the technical performance and real-world applicability of AI tools. This is especially crucial for titles and abstracts because these sections often influence first impressions and inform clinical decision-making.</p>

Unraveling the 'Spin' and Selective Reporting in Medical AI Research: A Cross-Sectional Meta-Research Study

<p>Joe D. Menke,<sup>1</sup> Mengfei Lan,<sup>1</sup> Halil Kilicoglu<sup>1</sup></p>
<h4>Objective </h4>
<p>The importance of self-acknowledged limitations (SALs) has long been recognized.<sup>1</sup> Prior work detecting<sup>2</sup> and categorizing<sup>3</sup> limitation statements using natural language processing (NLP) has made large-scale assessments of limitation reporting possible. By comparing SALs in research articles with limitations identified by systematic reviewers, this study aimed to evaluate the quality and coverage of SALs in relation to risk of bias.</p>
<h4>Design</h4>
<p> We constructed a dataset pairing SALs with limitations discussed by reviewers through risk-of-bias assessments. Articles from the Cochrane Database of Systematic Reviews available in the open-access subset of PubMed Central were downloaded in September 2024. For papers cited in these reviews, full texts were downloaded when available, and existing NLP models<sup>3</sup> were used to extract and classify sentences discussing limitations (December 2024). Identifying information and risk-of-bias assessments for cited articles were extracted from reviews’ Characteristics of Included Studies tables when a Risk of Bias section was present; reviews without this section were excluded. For living reviews, duplicate assessments were removed to retain only 1 assessment per cited article across versions of a living review. Risk-of-bias statements, originally in tabular form (eg, “Allocation concealment [Selection bias] High risk CBA; no allocation concealment done.”), were rephrased into natural language using a large language model (Llama3.3-70B). Low-risk components were excluded, retaining only high- and unclear-risk items. A random subset was manually reviewed to check for systematic issues, which did not reveal concerning patterns or hallucinations. Paraphrased information from reviews and SALs from cited papers were classified using NLP models that recognized limitations sentences and types.<sup>3</sup> We analyzed and compared the distribution of categorized limitations mentioned in both groups in an effort to assess the quality of SALs.</p>
<h4>Results</h4>
<p> From 145 reviews, we extracted and classified limitations statements for 803 cited articles (5.54 articles per review). From risk-of-bias tables, 3172 limitations were extracted (3.95 per cited article). From 750 cited articles, 136,290 sentences were processed and classified (170 per article), yielding 5616 SAL sentences (7.49 per article). No SALs were found in 53 articles. Categorized data are reported in <b>Table 25-1017</b>. Outcome measures were the most common SAL (69.12% of articles), while reviewers noted missing data as the most common high-risk limitation (33.75% of articles) and blinding as the most common unclear risk (48.19% of articles). On average, 56.67% of reviewer-identified limitations were not self-acknowledged, including 38.10% of high-risk and 53.01% of unclear-risk limitations.</p>

![](https://assets.underline.io/markdown_image/1/image/94ce029a42605d4892ff758a6a004f27.png)

<h4>Conclusions</h4>
<p> We present categorized limitations data and compared SALs with reviewer-derived limitations, showing that more than one-third of high-risk limitations are not self-acknowledged. Our findings may be used to better understand the quality of existing self-acknowledged limitations as well as highlight categories that are potentially underreported by authors.</p>

A Comparison of Self-Acknowledged Limitations With Risk-of-Bias Assessments From Systematic Reviews

<p>Kathryn A. Phillips,<sup>1,2</sup> Danea M. Horn<sup>1,2</sup></p>
<h4>Objective</h4>
<p> The move toward open science has focused attention on journal review and publication times,<sup>1</sup> particularly for health care research, where rapid dissemination is important for decision-making. We examined how academic journals that publish on health policy report and measure their review and publication times (RPTs) and assessed patterns across journals. Compared with earlier research that focused on article-level metrics for specialty journals,<sup>2</sup> we focused on journal-level metrics across a broad range of journals, enhancing generalizability.</p>
<h4>Design</h4>
<p> We conducted a cross-sectional analysis of 57 academic journals that publish on health policy topics following STROBE guidelines. Institutional review board review was not required. We included journals with a Google h5-index greater than 23 and a Clarivate impact factor of 2 or higher as of November 18, 2024. Final inclusion was based on review by 3 journal editors. We examined 6 metrics (<b>Table</b> <b>24-0820</b>) and used descriptive and statistical analyses to assess variation in the definition and reporting of RPTs. We compared RPTs across journal characteristics using the Wilcoxon rank sum test (with significance established at <i>P</i> &lt; .05).</p>

![](https://assets.underline.io/markdown_image/1/image/06280c0b892539b55c17e4d5a6db2179.png)

<h4>Results</h4>
<p> Of the 57 journals analyzed, 9 (15.8%) did not publicly report any RPTs. Conversely, only 21 journals (36.8%) reported 3 or more metrics. There was wide variation in each reported RPT, with the full peer-reviewed publication process taking 5.6 to 11.9 months. Open access journals had faster median submission to final decision (peer-reviewed) times compared with hybrid and subscription journals (184.5 vs 228.0 days; <i>P</i> = .03). Highly selective journals (journals with high impact factors and low acceptance rates) had a faster median time to first decision than less selective journals (3.0 vs 13.0 days; <i>P</i> &lt; .001). Within each RPT metric, there was considerable variation in reporting frequency and definitions. Journals often did not clarify whether the time to first decision included peer review and presented ranges or used qualifiers such as <i>typically</i> or <i>approximately</i> for post–peer review decision times. Few journals reported metrics by article type or provided metric time frames. Lastly, <i>mean</i> and <i>median</i> were used inconsistently.</p>
<h4>Conclusions </h4>
<p>There was substantial variation across journals in whether and how they report RPTs and selective reporting and considerable variation in how timing metrics were defined. Publication speed is influenced by multiple factors, including review processes and publication frequency. The lack of standardized reporting practices limits transparency in academic publishing and suggests a need for journals to more consistently report RPTs and for RPTs to be included in standardized databases and tracking systems. This would better inform author submission decisions and inform future research and testing of RPT interventions using data from editorial systems. Improving reporting and transparency is especially important for research on urgent health policy topics and for early-career academics.<sup>3</sup></p>

<h4>Objective </h4>
<p>Altmetric scores capture online engagement with research, including social media mentions and news coverage, whereas citation counts represent academic impact. It remains uncertain whether the source of funding for randomized clinical trials (RCTs) correlates with the online and academic impact of RCTs overall and within the subsets that meet or do not meet their prespecified primary outcomes. We hypothesized that privately funded trials, particularly those with positive results, would be cited more often and have higher Altmetric scores than publicly funded trials.</p>
<h4>Design </h4>
<p>We searched PubMed for cardiovascular RCTs published in <i>JAMA</i>, <i>The Lancet</i>,<i> </i>and<i> New England Journal of Medicine </i>between 2014 and 2019. This timeframe was selected to ensure sufficient follow-up for citation accrual and stability of Altmetric activity while capturing contemporary cardiovascular research. Trials were classified by funding source: public (ie, governmental), private (including for-profit industry and nonprofit organizations), or hybrid (with both public and private funding). RCT results were considered positive if they met their primary outcome or at least 1 of their coprimary outcomes and negative if they did not. Altmetric scores were obtained from Altmetric.com, and citation counts from Google Scholar (last accessed February 8, 2025). Both metrics were adjusted for publication year.</p>
<h4>Results </h4>
<p>A total of 435 cardiovascular RCTs were analyzed, of which 130 (29.9%) were publicly funded and 197 (45.3%) were privately funded (<b>Figure 25-1147</b>). A total of 175 negative trials (40%) were identified. There was no significant difference across trials for Altmetric score based on the funding source (median [IQR] scores: public, 218.1 [112.3-465.6]; private, 215.1 [112.9-506.6]; and hybrid, 244.5 [127.3-555.8]; <i>P</i> = .49). Publicly funded trials were cited less frequently than privately funded or hybrid-funded trials (median [IQR] citations: public, 410.0 [226.5-724.0]; private, 599.0 [287.0-1022.0]; and hybrid, 607.0 [301.8-936.0]; <i>P</i> = .003). When exploring the findings based on the primary results of the RCTs, median (IQR) citations for positive vs negative publicly funded trials (402.5 [216.3-827.0] vs 419.5 [240.3-644.0] citations) and hybrid trials (614.5 [311.8-1173.3] vs 597.0 [300.5-808.3] citations) were substantively similar, whereas median (IQR) citations for privately funded trials (705.0 [298.5-1395.5] vs 383.0 [262.3-694.8] citations) were higher if they met the primary outcome (<i>P</i> for interaction &lt; .001).</p>

![](https://assets.underline.io/markdown_image/1/image/01c2c8ab244adfa241066ffe3d0e10cc.png)

<h4>Conclusions </h4>
<p>Funding source was associated with subsequent citations, but not the Altmetric score. Publicly funded trials received significantly fewer citations than privately funded trials. Publicly and hybrid-funded trials showed similar citation patterns regardless of outcome, whereas privately funded trials were cited more when the primary outcome was met. These findings highlight the role of funding source in shaping the impact of cardiovascular RCTs.</p>

Funding Sources and the Online and Academic Impact of Cardiovascular Trials Published in Highest-Impact Journals

<p>Justin N. Nguyen,<sup>1</sup> Robert T. Rubin<sup>1,2</sup></p>
<h4>Objective</h4>
<p> Several issues about scientific publishing, including integrity of peer review, honorary/ghost authorships, commercial influences, and inadequate disclosure of conflicts of interest, have been receiving increasing scrutiny.<sup>1</sup> The question arises as to how often journal editors in chief (EICs) publish research and review articles in their journals during their tenure compared with before and after their editorships.<sup>2,3</sup> If psychiatry EICs are publishing significantly more often during their tenure, might they be taking advantage of their position in their own journals? Our null hypothesis was that psychiatry EICs do not favor their own journals for self-publication.</p>
<h4>Design</h4>
<p> As an exploratory study, EICs’ publishing practices were examined for 7 general and specialty psychiatry journals (<i>Amer J Psychiatry</i>, <i>Acta Neuropsychiatrica</i>, <i>Biol Psychiatry</i>, <i>Can J Psychiatry</i>, <i>JAMA Psychiatry</i>, <i>J Clin Psychopharmacology</i>, and <i>Neuropsychopharmacology</i>) and 7 general medicine journals (<i>Am J Med</i>, <i>Ann Int Med</i>, <i>Br Med J</i>, <i>Can Med Assoc J</i>, <i>JAMA</i>, <i>Lancet</i>, and <i>N Engl J Med</i>). Data collection occurred between October 2021 and August 2024. For each journal, 1 to 6 psychiatry and 2 to 5 medicine EICs were identified, depending on lengths of tenure. From PubMed, publication lists were compiled for each EIC tenure period, 5 years prior, and 5 years following. Articles related to editors’ responsibilities were omitted; only research and review articles (articles also appropriate for other journals) were included. Two-way analysis of variance with repeated measures was used to assess differences by specialty and time period (the repeated measure).</p>
<h4>Results</h4>
<p> This study included 450 articles published in psychiatry journals and 96 published in general medicine journals. The mean and median articles per year for each time period are presented in <b>Table 25-0853</b>. Psychiatry editors published several times more research and review articles in their own journals than did medicine editors. In addition, psychiatry editors published 128% more frequently in their own journals while in office vs before compared with 24% more frequently for medicine editors. Analysis of variance indicated that the differences in both journal type (F = 10.33; df = 1,33) and time periods (F = 6.26; df = 2,66) were significant (<i>P</i> &lt; .003 for both). Their interaction (F = 3.94; df = 2, 66) also was significant (<i>P</i> &lt; .02). A total of 4 of the 25 psychiatry EICs accounted for most of this difference, with one EIC having published 9 times more frequently in their journal vs before and after their tenure.</p>

<h4>Conclusions</h4>
<p> Psychiatry EICs published significantly more often when leading their journals, whereas medicine EICs did not. This finding has several important limitations. Selection of general medicine journals was subjective, and the medicine journals had higher Impact Factors, longer tenure of editors, and likely greater editorship responsibilities than the psychiatry journals. Articles with EICs as first, senior, and co-authors were included, and there may have been different author motivations for submission. We did not assess if the articles with EICs as authors included disclaimers about the role, or lack of role, of the EICs in editorial review and decision for these articles. Nevertheless, the increase in self-publishing occurred in a small number of psychiatry EICs. This should be further explored through study of a larger number of specialties, more closely matched journals, and more EICs.</p>
