目的研究1994年至2014年在高影响力的普通医学期刊上发表的原创研究的第一作者中女性代表性的变化，并研究期刊之间的差异。研究样本1994年2月至2014年6月期间，所有发表在Annals of Internal Medicine、Archives of Internal Medicine、The BMJ、JAMA、The Lancet和the新英格兰Journal of Medicine（NEJM）上的原创研究文章，每隔一个月一期。主要结果测量女性第一作者的患病率及其与出版时间和期刊的调整相关性，使用多变量logistic回归模型进行评估，该模型考虑了作者人数，研究类型和专业/主题，进行研究的大陆，以及期刊与出版时间，研究类型和大陆之间的相互作用。从这个模型的估计被用来计算调整后的比值比对平均值在六个期刊，95%的置信区间和P值来描述的协会interests. STSTThe的第一作者的性别被确定为3758的3860篇文章考虑; 1273（34%）是女性。调整后，女性第一作者从1994年的27%显著增加到2014年的37%（P
OBJECTIVETo examine changes in representation of women among first authors of original research published in high impact general medical journals from 1994 to 2014 and investigate differences between journals.DESIGNObservational study. Study sample All original research articles published in Annals of Internal Medicine, Archives of Internal Medicine, The BMJ, JAMA, The Lancet, and the New England Journal of Medicine (NEJM) for one issue every alternate month from February 1994 to June 2014.MAIN EXPOSURESTime and journal of publication. Main outcome measures Prevalence of female first authorship and its adjusted association with time of publication and journal, assessed using a multivariable logistic regression model that accounted for number of authors, study type and specialty/topic, continent where the study was conducted, and the interactions between journal and time of publication, study type, and continent. Estimates from this model were used to calculate adjusted odds ratios against the mean across the six journals, with 95% confidence intervals and P values to describe the associations of interest.RESULTSThe gender of the first author was determined for 3758 of the 3860 articles considered; 1273 (34%) were women. After adjustment, female first authorship increased significantly from 27% in 1994 to 37% in 2014 (P
