&lt;h4&gt;Objective&lt;/h4&gt;
&lt;p&gt; We aimed to describe researcher adherence to journal data sharing policies across health research. This included describing what factors increase intention to share data and how journal policies requiring data sharing impact intended data sharing.&lt;/p&gt;
&lt;h4&gt;Design&lt;/h4&gt;
&lt;p&gt; This was a cross-sectional study of all original research published in the highest-impact medical journals in 2022. Journals were included if they ranked among the top 5 in Impact Factor in 59 fields of medicine in the 2020 Journal Citation Reports, had a data sharing policy that either required or recommended sharing data, and published original research. Journal websites were searched to identify all original research published in 2022. Data were manually collected on study characteristics (study type, industry involvement, and COVID-19 relevance) and data sharing plans (data sharing statements and data sharing intentions extracted from publicly available research protocols and articles). Articles were descriptively analyzed by these journal data sharing policies, study characteristics, and data sharing plans.&lt;/p&gt;
&lt;h4&gt;Results&lt;/h4&gt;
&lt;p&gt; Of 134 journals included, 36 (27%) required data sharing and 98 (73%) recommended data sharing. The analysis included 1868 interventional studies (1383 randomized clinical trials [74%] and 485 nonrandomized trials [26%]) and 10,368 observational studies (4814 cohort studies [46%], 4166 cross-sectional studies [40%], 1100 case-control studies [11%], and 288 case series/reports [3%]). Publicly available research protocols were available for 1993 of 10,243 studies (16%), of which 1153 (58%) had an initial data sharing statement. Only 1023 interventional studies (55%) and 4511 observational studies (44%) in journals that recommended or required data sharing actually intended to share data. Most studies only intended to share data underlying the published results with researchers, for purposes and by mechanisms at the discretion of and subject to approval by the principal investigator and without supporting documents or specified timeframes. Factors associated with increased intention to share data included journal policies that required data sharing and data sharing statements as well as industry involvement and COVID-19 relevance for interventional studies. For journals with policies that required data sharing, researchers were more likely to share more data (ie, all data collected during the study) and supporting documents (ie, supporting documents) in a timelier manner (ie, immediately following publication and indefinitely) to more people (ie, to anyone who wishes to access the data) for more purposes (ie, for any purpose) and by easier means (ie, with unrestricted access through a third-party website).&lt;/p&gt;
&lt;h4&gt;Conclusions&lt;/h4&gt;
&lt;p&gt; Journals that required data sharing had higher rates of studies that intended to share data compared with journals that only recommended data sharing. However, most studies that intended to share data had restrictions on sharing. In addition to requiring data sharing and data sharing statements, journals should define and explain data sharing and individual participant data, better review data sharing statements and the reasonableness of justifications to not share data, and provide additional guidance on the operationalization of data sharing in accordance with best practice.&lt;/p&gt;

<h4>Importance </h4>
<p>Authorship is the currency of academia and research, but it is not only about recognition. It brings accountability and transparency and can have ethical and legal implications.</p>
<h4>Observations </h4>
<p>Starting from the call for contributors to replace authors by Drummond Rennie and his colleagues almost 30 years ago,<sup>1</sup> the evolution of scientific authorship and contributorship models will be presented. Current challenges to authorship will also be explored, from paper mills to artificial intelligence.</p>
<h4>Conclusions </h4>
<p>Authorship has not been replaced by contributorship and will need a systemic approach to balance scientific credit, career advancement, and ethical responsibility.</p>

Forward to the Past - Making Contributors Accountable

<p>Isamme AlFayyad,<sup>1</sup> Maurice Zeegers,<sup>2</sup> Lex Bouter,<sup>3</sup> Helen Macdonald,<sup>4</sup> Sara Schroter<sup>4</sup></p>
<h4>Objective </h4>
<p>Recent surveys report that a high percentage (50%-76%) of researchers use artificial intelligence (AI) in their research.<sup>1,2</sup> In April 2024, BMJ Group mandated submitting authors to disclose and describe their use of AI.<sup>3</sup> We analyzed the frequency of self-disclosed use of AI in research manuscripts submitted to 49 BMJ Group biomedical journals and identified types of AI tools used and the tasks they assisted with. We also compared the characteristics of manuscripts disclosing AI use compared with those not disclosing it.</p>
<h4>Design </h4>
<p>A cross-sectional analysis of original research submitted between April and November 2024 was conducted and reported using the STROBE reporting guideline. Main study outcomes were frequency of self-disclosed use of AI, types of AI tools used, and tasks they assisted with. Characteristics of submissions (region of submitting author, number of authors, acceptance rate, impact factor, general medical/specialty journal, peer review model) were extracted from journals’ manuscript tracking systems and websites. χ² test was used to compare proportions of these characteristics between submissions disclosing and not disclosing AI use. Factors associated with disclosing AI use were assessed using binomial logistic regression. A <i>P</i> value threshold for significance was set at .05.</p>
<h4>Results </h4>
<p>There were 25,114 eligible submissions from Asia (13,505 [53.8%]), Europe (6523 [26.0%]), North America (2795 [11.1%]), Africa (1196 [4.8%]), Oceania (708 [2.8%]), and South America (387 [1.5%]). A total of 1431 of 25,114 submissions (5.7%) disclosed AI use. The most common types of AI tools used were generative AI chatbots (812/1431 [56.7%]), writing assistant tools (182 [12.7%]), and visual/image processing tools (38 [2.7%]) (<b>Table 25-1013</b>). The majority of submitting authors who disclosed AI use reported using it to improve the quality of their writing (1248/1431 [87%]), and 28% (n = 399) reported using it for other purposes, including translation (107 [7.5%]), analyzing or collecting data (44 [3.1%]), generating data and output (87 [6.1%]), code writing (15 [1.0%]), image processing (36 [2.5%]), literature searches (49 [3.4%]), and managing references (8 [0.6%]). The percentage of submissions with disclosed AI use varied significantly by region (highest in Europe: 31.0%; lowest in Oceania: 1.0%; <i>P</i> &lt; .001). Submissions disclosing AI use had a lower mean number of authors (8.39 vs 8.90; <i>P</i> = .005). Authors from Europe (odds ratio [OR], 3.61 [95% CI, 2.11-6.18]), North America (OR, 2.30 [95% CI, 1.32-4.02]), South America (OR, 4.93 [95% CI, 2.62-9.28]), Asia (OR, 2.87 [95% CI, 1.68-4.89]), and Africa (OR, 3.34 [95% CI, 1.92-6.08]) were significantly more likely to disclose AI use than those from Oceania (<i>P</i> &lt; .05 for all). Conversely, each additional author reduced disclosure odds by 1% (OR, 0.99 [95% CI, 0.97-0.99]). Other characteristics of the journal (acceptance rate, impact factor, general medical/specialty journal, and peer review model) were not associated with AI use disclosure.</p>

<h4>Conclusions </h4>
<p>The percentage of submitted articles with self-disclosed AI use was significantly lower in this study than what has been reported in recent surveys of researchers about their general use. Submitting authors may be underreporting their use of AI. </p>

Authors Self-Disclosed Use of Artificial Intelligence in Research Submissions to 49 BMJ Group Biomedical Journals

<p>Roy H. Perlis,<sup>1,2</sup> Annette Flanagin,<sup>3</sup> Jacob Kendall-Taylor,<sup>3</sup> Michael Berkwits,<sup>4</sup> Kirsten Bibbins-Domingo<sup>3</sup></p>
<h4>Objective </h4>
<p>The scientific community is divided about the appropriate role of artificial intelligence (AI) in manuscript preparation.<sup>1</sup> In 2023, JAMA Network journals began requiring authors and reviewers to answer questions about use of AI to create or assist in the creation or editing of submitted manuscripts or with preparation of reviews.<sup>2</sup> This study was conducted to assess author and reviewer declarations of such use.</p>
<h4>Design </h4>
<p>Study of manuscripts and peer reviews submitted to 13 JAMA Network journals from September 2023 to May 2025. Numbers and proportions of manuscripts with corresponding authors and peer reviewers declaring use of AI were examined, along with factors associated with use (eg, journal, country, article type). For authors’ use, reasons, type of AI, and editorial decisions were also assessed; for reviewers’ use, turnaround time and ratings of reviews were assessed. Where sample sizes were sufficient, logistic regression models were run, with use of AI as the dependent variable and article type, journal, and review outcome as independent variables. A 2-sided uncorrected <i>P</i> value of &lt;.05 was considered the threshold for statistical significance. This study was deemed exempt from ethical approval by the Mass General Brigham Institutional Review Board.</p>
<h4>Results </h4>
<p>Of 82,829 manuscripts submitted during the study period, 2257 (2.7%) declared AI use. Authors’ use of AI increased from 1.6% in September 2023 to 4.2% in May 2025 (<i>r</i><sup>2</sup> = .34; <i>P</i> &lt; .01). <b>Table 25-1115</b> contrasts manuscripts with or without disclosed AI use by author country, journal, manuscript type, study type, editorial decision, AI use categories, and common AI models used. Author AI use was highest in <i>JAMA Network Open</i> (4.1%) and <i>JAMA</i> (3.1%) and lowest in <i>JAMA Dermatology</i> (1.6%) and was highest among authors from Taiwan (7.2%). Letters to the Editor (odds ratio [OR] 1.63, 95% CI 1.37-1.94) and Viewpoints (OR 1.44, 95% CI 1.21-1.72) were more likely to involve AI use than Original Investigations. The most common reported reasons for AI use by authors were for language and editing (50.0%), data analysis and statistics (11.8%), and content generation and drafting (8.2%). ChatGPT was the most common AI model used by authors (62.9%). Mean (SD) reviewer turnaround times were 11.8 (8.5) days for those who did not disclose AI use and 12.6 (7.6) days for reviewers who disclosed AI use. Reviewer use of AI was highest for <i>JAMA Network Open</i> (0.9%) and <i>JAMA Psychiatry</i> (0.8%) and among reviewers from the UK (2.7%).</p>

<h4>Conclusions </h4>
<p>Among manuscripts submitted to 13 major medical journals, author declaration of AI use to create or edit content was low but more than doubled during the study period and varied by journal and article type. Very few reviewers disclosed use of AI, possibly because of guidance forbidding such use.<sup>3</sup> Limitations include small numbers of reported AI use, which limited comparisons for some factors, and the likelihood of underreporting of AI use.</p>

Factors Associated With Author and Reviewer Declared Use of AI in Medical Journals

<p>Elena Álvarez-García,<sup>1</sup> Daniel Garcia-Costa,<sup>1</sup> Flaminio Squazzoni,<sup>2</sup> Mario Malički,<sup>3,4,5</sup> Bahar Mehmani,<sup>6</sup> Francisco Grimaldo<sup>1</sup></p>
<h4>Objective </h4>
<p>While the publication of review reports increases the transparency of peer review, little is known about the effect it has on the content or quality of reports.<sup>1</sup> The objective of our study was to assess differences in length, information content, and similarity of open vs unpublished reports. </p>
<h4>Design </h4>
<p>This was a cross-sectional study following STROBE guidelines for reporting<sup>2</sup> that compared open with unpublished reports from 233 medical journals from Elsevier and Springer Nature, submitted from 2016 to 2021. Reports were obtained through confidential agreements with the publishers. Content of reports was compared using number of sentences, previously validated models for classification of 8 categories of content,<sup>3</sup> information content score (mean cumulative distribution function values of each category’s sentence count, based on a zipfian distribution, with scores ranging from 0 to 1, where 1 indicates the highest informativeness), and information score dispersion measured by the Gini index (measure of similarity between reports for the same manuscript, where 0 indicates total similarity and 1 indicates total dissimilarity). Number of sentences, information score, and dispersion were compared using Mann-Whitney <i>U</i> tests. The association of information score and Gini index with peer review type, journal quartile of impact factor, and reviewer gender, seniority, and region were explored using generalized linear models. To adjust for multiple comparisons, we considered <i>P</i> &lt; .001 as statistically significant.</p>
<h4>Results</h4>
<p> Compared with unpublished reports (n = 117,250), open peer review reports (n = 40,844) were longer (median [IQR] length, 22 [12-37] sentences vs 17 [10-28] sentences; <i>P</i> &lt; .001) than unpublished reports and had a higher informative content (median [IQR] score, 0.52 [0.35-0.70] vs 0.46 [0.30-0.65]; <i>P</i> &lt; .001), with the largest difference found in the number of suggestion and solution sentences (Figure 25-1081</b>). Women’s reports had a higher information score than men’s reports (difference, 6.3%), and reviewers from non-Western institutions had lower scores than those from Western institutions (difference, −6.0%). Open peer review reports were also more similar to each other (median [IQR] Gini index, 0.19 [0.09-0.33] vs 0.22 [0.11-0.35]; <i>P</i> &lt; .001).</p>

![](https://assets.underline.io/markdown_image/1/image/6f7beaaf8f16b79237fbcb5ba46ff349.png)

<h4>Conclusions </h4>
<p>Our study showed that open peer review reports were longer than traditional unpublished reports, with the greatest differences found in the number of suggestion and solution sentences. These results suggest that increasing the transparency of peer review could lead to more detailed reports that focus on manuscript improvement. <br />A limitation of our study is that we did not have access to published manuscripts and were unable to determine the impact of initial quality of manuscripts beyond journal ranking, nor the impact peer review reports had on manuscript improvement.</p>

<h4>Objective </h4>
<p>We examined whether a funder-led open science policy and compliance workflow could increase the deposition and unambiguous identification of research data, code, protocols, and key laboratory materials (eg, cell lines, antibodies).</p>
<h4>Design </h4>
<p>A cross-sectional study was conducted on articles supported by the Aligning Science Across Parkinson’s (ASAP) Collaborative Research Network (CRN) and published between January 1, 2024, and April 30, 2025 (N = 102). The study was exploratory, and thus was not registered, and does not present inferential statistics. ASAP has a thorough Open Science Policy<sup>1</sup> and Compliance Workflow,<sup>2</sup> which require grantees to send manuscript drafts to ASAP staff, post preprints, deposit research outputs, and unambiguously identify research inputs. The workflow is managed by an ASAP staff member who integrates automated and manual assessments to provide a grantee with systematic feedback outlining the actions required to align their manuscript draft with the ASAP Open Science Policy.</p>
<h4>Results </h4>
<p>Between the version of a manuscript first shared with ASAP staff and the associated final publication, there were substantial increases in the deposition of newly generated datasets (21% for the first version to 88% for the published version), unambiguous identification of reused datasets (72% to 86%), deposition of newly generated code (15% to 72%), unambiguous identification of software used (35% to 79%), registration of newly generated key lab materials (22% to 78%), unambiguous identification of key lab materials used (44% to 87%), and deposition of newly generated protocols and unambiguous identification of existing protocols (35% to 81%; data on protocols was collapsed) (<b>Table 25-0892</b>). Of the included publications, 98% (100 of 102) had an associated preprint. Preprints were posted a median (IQR) of 4 (−7 to 50) days before submission to the journal in which they were eventually published and 236 (150-328) days before they were published in a journal. To facilitate this workflow, grantees share each manuscript alongside a Key Resource Table that lists persistent identifiers for the associated datasets, code, software, protocols, and key lab materials. Collating these Key Resource Tables provides a living and near-comprehensive log of all the inputs and outputs from ASAP CRN–funded research.</p>

A Funder-Led Intervention to Increase the Sharing of Data, Code, Protocols, and Key Laboratory Materials

<p>Kyobin Hwang,<sup>1</sup> Zexing Song,<sup>2,3</sup> Marsida Stafa,<sup>3</sup> Jodie Chiu<sup>,4</sup><sup> </sup>An-Wen Chan<sup>1,3,5</sup></p>
<p><h4>Objective</h4> We aimed to determine how often medical journals have policies requiring clinical trial registration, adherence to reporting guidelines, and participant-level data sharing. We also evaluated associations between journal characteristics and the existence of such policies for clinical trial manuscripts.</p>
<p><h4>Design </h4>A PubMed search using the clinical trial filter was conducted to identify journals that published at least 20 trials in 2023. We extracted publicly available data from journal websites, including policies on trial registration, adherence to reporting guidelines, trial protocol submission requirements, and availability of participant-level data. A practice was classified as required if the policy used words such as must, need, or should. Policies using language such as encouraged and preferred were classified as recommended practices. For each journal, we recorded the 2023 Clarivate impact factor, journal scope (general vs specialty), and publishing model (purely open access vs other). We calculated descriptive statistics to summarize the prevalence of transparency policies and used multivariable logistic regression to assess the association between journal characteristics and policy requirements.</p>
<h4>Results</h4>
<p> Among 380 included journals, 320 (84%) required trial registration, 11 (3%) recommended it, and 49 (13%) did not mention it. Adherence to a reporting guideline for clinical trials was required by 251 journals (66%), recommended by 74 (19%), and not mentioned by 55 (14%). Trial protocol submission was required by 118 (31%), recommended by 110 (29%), and not mentioned in 152 (40%). Public availability of participant-level datasets was required by 104 (27%), recommended by 218 (57%), and not mentioned by 58 (15%). A description of the data sharing plan was required by 212 journals (55.8%), recommended by 110 (28.9%), and not mentioned by 58 (15.3%). Purely open access journals had a 4-fold higher odds of requiring trial registration (adjusted odds ratio [AOR], 4.02; 95% CI, 1.41-15.59) and protocol submission (AOR, 4.13; 95% CI, 2.17-8.37) and 2.5 times higher odds of requiring public sharing of participant-level data (AOR, 2.46; 95% CI, 1.03-7.04) compared with other journals (<b>Table 25-1183</b>). Each 5-point increase in journal impact factor was associated with a more than 2.5-fold increase in the odds of requiring trial registration (AOR, 2.65; 95% CI, 1.45-5.98) and over 50% increase in the odds of requiring protocol submission (AOR, 1.56; 95% CI, 1.26-2.03). Impact factor was not significantly associated with requiring data sharing. No significant associations were found for journal scope or volume of trials published.</p>

![](https://assets.underline.io/markdown_image/1/image/1f3e3ae7eedf2cd146453708cac3c6fc.png)

<h4>Conclusions</h4>
<p> Journal policy requirements vary substantially in supporting best practices for clinical trial transparency. Journals with a purely open access publishing model and higher impact factor were more likely to adopt transparency policies. These findings highlight the need for improved editorial standards across the publishing landscape to promote transparency and reduce research waste.</p>

Medical Journal Policies on Requirements for Clinical Trial Registration, Reporting Guidelines, and Data Sharing: A Systematic Review

<p>M. Janina Sarol,<sup>1</sup> Jodi Schneider,<sup>1,2</sup> Halil Kilicoglu<sup>1</sup></p>
<h4>Objective </h4>
<p>An estimated 25% of citations in medical journals are inaccurate.<sup>1</sup> If not corrected, these citation quotation errors can propagate misinformation and establish unfounded claims.<sup>2</sup> Correcting them before publication is vital, yet citation accuracy is overlooked in the peer review process. The prevalence of citation quotation errors in the biomedical literature also remains unclear, because existing studies rely on manual evaluation on a limited set of articles.</p>
<h4>Design </h4>
<p>We explored the use of large language models, specifically Gemini 1.5 Pro, GPT-4o (gpt-4o-2024-08-06), and LLaMA-3.1 (8B and 70B), to automatically identify citation quotation errors. We compared 2 approaches. In the first, we supplied the prompt with the citation in question, the paragraph containing the citation, and the full reference article. The second approach consists of a 3-step procedure and mimicked how a human reviewer might perform the task manually by first identifying the citation context, then locating relevant sentences in the reference article, and finally assessing citation accuracy. Specifically, the procedure consists of (1) extracting the citation sentence, (2) retrieving the 50 most relevant sentences using the MedCPT retriever model and reranking them with a fine-tuned MonoT5 model to select the top 5 sentences, and (3) verifying the citation accuracy with the large language model (<b>Box 25-1015</b>). Both approaches were evaluated from November 2024 to January 2025 using a citation quotation error dataset,<sup>3</sup> the first publicly available corpus of its kind (Cohen κ for interrater agreement: 0.96 for citation context and 0.31 for accuracy detection). The better-performing approach was applied to assess 2898 citations from 2000 articles to the 100 most cited PubMed Central Open Access (PMC-OA) articles (24 different journals).</p>

![](https://assets.underline.io/markdown_image/1/image/e80718c94a9aa238f09a1d74fc02135d.png)

<h4>Results </h4>
<p>Gemini 1.5 Pro yielded best performance, obtaining an accuracy of 69% with both approaches. It outperformed GPT-4o slightly, while LLaMA-3 failed to generate meaningful results with the first approach and performed poorly with the second. Because the first approach only identified 25% (55 of 220) of the erroneous citations and the 3-step procedure identified 51% (113 of 220), the second approach was applied to the subset of PMC-OA articles. In the PMC-OA subset, 34% (981 of 2898) of the citation instances were assessed as erroneous. A total of 37% (742 of 2000) of citing articles were found to contain citation quotation errors; 98% (98 of 100) of reference articles were cited incorrectly at least once.</p>
<h4>Conclusions </h4>
<p>Our preliminary results confirm the high prevalence of citation quotation errors in the medical literature. We will present a more comprehensive analysis of citation quotation errors in the PMC-OA subset at the conference. Automated verification of citations could help journals and peer reviewers identify questionable citation practices and reduce propagation of misinformation, improving the trustworthiness of scientific evidence.</p>

Leveraging Large Language Models for Detecting Citation Quotation Errors in Biomedical Literature

<p>Bojan Batalo,<sup>1</sup> Erica K. Shimomoto,<sup>1</sup> Neil Millar<sup>2</sup></p>
<h4>Objective </h4>
<p>Promotional language (hype) in biomedical research writing has increased significantly over the past 40 years and has potential to influence readers’ perceptions and evaluations of evidence.<sup>1-3</sup> Automatic systems capable of detecting and providing feedback on hype may offer a means to foster more objective reporting. However, the absence of formal guidelines for identifying hype represents a barrier for human annotators and the development of such systems. This pilot study develops formal guidelines for classifying hype and evaluates the application of annotated data to automate hype detection via machine learning.</p>
<h4>Design </h4>
<p>Annotation guidelines were developed to classify 11 adjectives commonly associated with novelty and potential hype (eg, <i>creative</i>, <i>first</i>, <i>groundbreaking</i>, <i>innovative</i>). Guidelines followed the following hierarchical decisions: (1) does the adjective imply a positive value judgment?; (2) is it hyperbolic?; (3) is the adjective gratuitous (ie, adds little to the content), amplified (strengthened by modifiers), or coordinated (paired with other promotional adjectives)?; and (4) is the broader sentential context promotional? A total of 550 sentences containing the adjectives (50 per adjective) were randomly sampled from National Institutes of Health grant abstracts funded between 2016 and 2020 and independently annotated by a linguist and 2 computer scientists, with disagreements resolved through discussion, providing the criterion standard. Our choice of grant abstracts as the starting point for our research is due to the highly competitive nature of research funding.<sup>1</sup> The annotated data were split 80:20 into development and hold-out test sets; machine learning algorithms were trained on the development and evaluated on the test set. Additionally, a human baseline was established by an additional researcher blinded to the annotation guidelines but supplied with a broad definition of hype, manually classifying the test set. Experiments tested 4 traditional text classification methods (multinomial Naive Bayes, multivariate Bernoulli Naive Bayes, latent semantic analysis, and support vector machines), with bag-of-words and averaged global vectors for word representation (GloVe) word embeddings as input features (<b>Table 25-0929</b>). Performance was evaluated using accuracy, weighted precision, recall, and F1 scores.</p>

![](https://assets.underline.io/markdown_image/1/image/334927ffdad7b95527ef7831f37feb90.png)

<h4>Results </h4>
<p>Excluding 13 sentences due to nonadherence with the guidelines, the final sample comprised 537 reliably annotated sentences (Cohen κ &gt; 0.94), of which 392 were classified as hype. Among machine learning models, GloVe-based support vector machines outperformed others with an accuracy of 79.6%, approximating the human baseline of 82.4%.</p>
<h4>Conclusions </h4>
<p>The annotation process underscored the subjective nature of assessing promotional language, particularly for context-dependent adjectives like <i>emerging</i> and <i>latest</i>, and the need for refined constructs to capture gradations of promotional language. Despite these limitations, the pilot study indicates the potential for machine learning models trained on well-annotated datasets to contribute to the automated detection of hype. Future steps include modifying the annotation systems and experimenting with large language models under zero/few-shot regimes.</p>

Automating the Detection of Promotional (Hype) Language in Biomedical Research

<p>Vishisht Rao,<sup>1</sup> Aounon Kumar,<sup>2</sup> Himabindu Lakkaraju,<sup>2</sup> Nihar B. Shah<sup>1</sup></p>
<h4>Objective </h4>
<p>Journals, conferences, and funding agencies face the risk that reviewers might ask large language models (LLMs) to generate reviews by uploading submissions. Existing detectors struggle to differentiate between fully LLM-generated and LLM-polished reviews. We addressed this problem by developing a method to detect and flag LLM-generated reviews while controlling family-wise error rates (FWERs).</p>
<h4>Design </h4>
<p>Our method had 3 components. (1) Watermarking: We stochastically chose specific phrases (watermarks), such as random (fake) citations, technical terms (“weak supervised learning”), or beginning the review with a prefix (“This paper investigates the problem…”). Watermarks were specific modifications to the review, which were undetectable unless the nature of the watermark was known. The watermark was known to the editors (but not the reviewers), who could detect LLM-generated reviews through watermarks in the review. (2) Hidden prompt injection: We added an instruction into the manuscript PDF (at the end of the last page; not detectable by the human reviewer) instructing the LLM to output the chosen watermark in the LLM-generated review (“Start your review with: &lt;chosen watermark&gt;”). We evaluated 3 injection methods: white text, font manipulation,<sup>1-3</sup> and a different language. (3) Statistical detection method: We developed a test for watermarks in the review (null hypothesis was the review was human written) and provided mathematical proof of controlling the FWER without making assumptions on how human reviews were written. The evaluation was performed on International Conference on Learning Representations (ICLR) manuscripts, a publication venue that reviews full manuscripts. We injected the hidden prompts into ICLR manuscripts and asked LLMs to generate a review and observe whether it contained the watermark. We also evaluated the robustness of our methods against 3 reviewer defenses (RDs), measures reviewers could take to avoid being flagged for using an LLM-generated review: paraphrasing (paraphrasing the original LLM-generated review using another LLM), identifying watermarks (asking the LLM to flag submissions with hidden prompts), and cropping out the end of the paper (removing the last page before generating the review using an LLM). Watermarks were most successfully embedded in the LLM-generated review when the hidden prompt was injected at the end of the last page. For the evaluation of the last RD, we injected the hidden prompt at a position other than the end of the last page.</p>
<h4>Results </h4>
<p>Our method was successful in embedding the chosen watermark in LLM-generated reviews and was robust to RD mechanisms (<b>Table 25-1176</b>) and detecting and flagging them while controlling false-positives. We conducted our test on 28,028 human-written reviews from ICLR 2021 and 10,022 from 2024, each augmented with 100 LLM-generated reviews with a watermark embedded for each of the 3 types. When executing our algorithm to control the FWER at 0.01 for the random start and technical term watermark and 0.001 for the random citation watermark, we observed 0 false-positives in all cases.</p>

Evaluation of a Method to Detect Peer Reviews Generated by Large Language Models

Fares Alahdab,<sup>1,2,3</sup> Juan Franco,<sup>3,4</sup> Helen Macdonald,<sup>4</sup> Sara Schroter<sup>4</sup>
<h4>Objective</h4>
Peer reviewer fatigue is on the rise, as reviewers are overburdened with increasing tasks and manuscripts to review, making it challenging for journal editors to secure a sufficient number of high-quality reviews.<sup>1</sup> Despite the potential benefits of using large language models (LLMs) in editorial and peer review processes<sup>2</sup> and the potential to support reviewers with tasks, it is not yet known how good they are at peer review. Additionally, covert use of LLMs in peer review is increasingly suspected, with limited knowledge of positive or negative impact. We aim to compare the quality and comprehensiveness of peer reviews produced by 5 LLMs compared with peer reviewers for research submissions.
<h4>Design</h4>
A comparative study of peer reviews produced by LLMs (GPT4o, GPTo3, Claude 3.5, Gemini 1.5 Pro, and Gemini 2.0 Flash) compared with 2 human peer reviews for research submissions between May 2024 and June 2025. Manuscripts were uploaded to Google’s Vertex AI, a private and secure BMJ Group workspace for using LLMs; the same prompt was used for all submissions (single-shot prompting). An experienced editor performed the ratings of all LLM and human reviews using the Review Quality Instrument (RQI),<sup>3</sup> a tool for assessment of review quality comprising 8 questions, each on a 5-point Likert scale. Secondary outcomes include a comprehensiveness score, based on elements of the manuscript that the reviews focused on, and whether they were evaluative in nature. Additionally, once the first decision has been made on the manuscripts, we plan to invite authors to complete a survey about their perceptions of both the LLM review reports and the peer reviewer reports for their manuscripts. We also plan to have a second editor perform the ratings and compute interrater agreement. Reviews produced by LLMs are not included in the decision-making for the manuscripts. Wilcoxon rank sum tests were used to compare LLM and human scores for each RQI item.

<h4>Results</h4> Preliminary data include 35 reviews (25 by LLMs and 10 by peer reviewers) of 5 BMJ submissions. Across 8 RQI items, LLM-generated reviews had higher mean (SD) scores than human reviewers on identifying strengths and weaknesses (4.12 [0.53] vs 2.70 [0.95]; P &lt; 0.001); providing useful comments on the writing, organization, tables, and figures (3.72 [0.79] vs 1.80 [0.63]; P &lt; .001); and constructiveness (4.00 [0.58] vs 3.00 [1.05]; P = .004) (<b>Table 25-1146</b>). Complete data will include 200 submissions to 4 BMJ journals, the secondary outcomes, and authors’ feedback on the LLM reviews.

![](https://assets.underline.io/markdown_image/1/image/b23f8733c131796f4e73f037ea693a62.png)

<h4>Conclusions</h4>
LLM-generated reviews matched or exceeded human reviewers on a few key dimensions of review quality. A fuller analysis will shed more light on the potential value of LLM peer reviews and how they could complement human peer reviewers’ work.
