    Background Gender disparities in scientific authorship are well documented, yet little is known about gender representation among authors of retracted publications. Methods We analyzed 878 retracted publications from 131 high-impact medical journals across nine clinical disciplines (anesthesiology, dermatology, general internal medicine, gynecology/obstetrics, neurology, oncology, pediatrics, psychiatry, and radiology). Gender was inferred using Gender API for all, first, and last authors. Two analytic samples were constructed based on prediction confidence thresholds (≥60% and ≥70%). We examined gender distribution across authorship positions, number of retractions per author, and disciplinary representation. Wilcoxon rank-sum and chi-squared tests were used to assess group differences. Gender proportions were compared with publication benchmarks from 2008–2017, restricting retraction data to the same period for comparability. Results Among 4,136 authors, 3,909 had full first names, and gender could be assigned to 3,865 (98.9%). In the sample with prediction confidence ≥60% (n = 3,743), 863 (23.1%) were identified as women. They accounted for 16.5% (123/747) of first and 12.7% (87/687) of last authors. They had significantly fewer retractions per author and were less likely to have >5 retractions (all authors: 3 women [8.1%] vs 34 men [91.9%], p < 0.001). Across most disciplines, their representation was below publication benchmarks. Dermatology (retractions = 80.0%, publications = 48.9–51.8%) and radiology (retractions = 40.0%, publications = 31.0-36.8%) were exceptions among first authors, while pediatrics (retractions = 50.0%, publications = 37.0%−42.6%) was an exception among last authors, though all based on small numbers. Conclusions Women are markedly underrepresented among authors of retracted publications, particularly in cases involving multiple retractions. Further research is needed to clarify underlying mechanisms.

    BACKGROUND: Besides the number of publications, the number of citations is another key metric often used to compare researchers with each other. While women researchers tend to have fewer publications than their men colleagues, the data is scarce for the number of citations. We aimed to determine whether there is a gender gap in citations. METHODS: We used Web of Science to retrieve the number of citations per year for all research articles and reviews published between January 2015 and December 2019 in fourteen high-impact general medical journals (impact factor > 5). We used Gender API to identify the gender of the first/last authors. We compared the results by gender using multivariable negative binomial regressions (adjusting for intra-cluster correlations within journals). RESULTS: The gender of the first/last author was determined for 13,218/13,350 (99%) and 11,894/12,026 (99%) articles, respectively. The proportion of women among first/last authors was 40% and 29%, respectively. The median number of citations per year was 5 (IQR = 11.3) for women and 6.8 (IQR = 17.8) for men for first authors (IRR = 1.5 [95% CI = 1.3-1.8], p value < 0.001), and 6 (IQR = 12.4) and 7.5 (IQR = 17.4) for last authors (IRR = 1.3 [95% CI = 1.2-1.5], p value < 0.001). Articles whose first and last authors were women were the least cited and those whose first and last authors were men were the most cited. CONCLUSION: In this cross-sectional study, we found that articles authored by women were cited less often than those authored by men. Further studies are needed to explore the reasons for these gender differences in article citations.
