The aim of the study was to explore female authorship in various aspects of randomized controlled trials (RCTs) in dentistry. A search was performed in PubMed for RCTs, in dentistry, indexed from 12/31/2016 to 12/31/2021. Only studies in English were considered. Data selection and extraction were performed by two authors and the following data collected: year of publication, journal, subject, number and names of authors, and country and gender (Genderize website) of the first 10 authors. Descriptive analyses, graphs, and maps were generated. Poisson regression assessed the influence of continent and year of publication on the presence of women as first or last authors. The results were presented as prevalence ratios (PR) and 95% confidence intervals (95%CI). A total of 844 RCTs and 4,305 authors (2,372 men and 1,662 women) were included. Gender disparity increases as the order of authorship advances. Among first authors, men represent 50.59% and women 44.08%, whereas among last authors, they account for 61.92% and 34.03%, respectively. Analyses showed no association between year of publication and the presence of women as authors. There were fewer women as first authors in Europe (PR: 0.82, 95%CI: 0.68-0.99) and as last authors in Europe and Asia (PR: 0.68, 95%CI: 0.53-0.87 and PR: 0.79, 95%CI: 0.63-0.99, respectively). The findings highlight a lower presence of female authors in all aspects analyzed in the RCTs, especially in last authorship. Also, there has been no indication of improvement in recent years. Female participation in RCTs is crucial not only for gender equity but also as a means to enhance the quality and relevance of clinical data for decision-making.
本研究的目的是探讨牙科随机对照试验（RCT）各方面的女性作者情况。在PubMed中检索了2016年12月31日至2021年12月31日索引的牙科RCT。仅考虑英文研究。由两名作者进行数据选择和提取，并收集以下数据：发表年份、期刊、主题、作者数量和姓名，以及前10位作者的国家和性别（Genderize网站）。生成了描述性分析、图表和地图。泊松回归评估了大陆和发表年份对女性作为第一或最后作者的影响。结果以患病率比（PR）和95%置信区间（95%CI）表示。共纳入844项RCT和4305名作者（2372名男性和1662名女性）。随着作者排名的推进，性别差距增大。在第一作者中，男性占50.59%，女性占44.08%；而在最后作者中，男性分别占61.92%和34.03%。分析表明，发表年份与女性作为作者的情况之间没有关联。在欧洲，女性作为第一作者的比例较低（PR：0.82，95%CI：0.68 - 0.99），在欧洲和亚洲，女性作为最后作者的比例较低（PR分别为：0.68，95%CI：0.53 - 0.87；PR：0.79，95%CI：0.63 - 0.99）。研究结果凸显了在RCT分析的所有方面，女性作者的比例较低，尤其是在最后作者这一位置。此外，近年来没有改善的迹象。女性参与RCT不仅对性别平等至关重要，也是提高临床数据质量和相关性以用于决策的一种手段。
