Gender disparities in research grant funding persist in many disciplines. With use of the Dimensions database, we sought to examine the extent of gender disparities in U.S. orthopaedic grant funding from 2010 onward. Our aim was to provide insights into the extent of gender disparities in the field of orthopaedic research and to highlight the potential need for future action to address these disparities.
Using orthopaedic-related search terms, we queried all U.S. grants awarded for orthopaedic research from 2010 to 2022. A total of 22,326 results were then manually screened to exclude those without a direct focus on orthopaedic research. The amounts received per principal investigator were reported in U.S. dollars and adjusted for inflation. Author gender was predicted with use of the Genderize.io algorithm application programming interface. The iCite Relative Citation Ratio (RCR) was utilized to assess the impact of the publications linked to each grant.
A total of 1,723 grants were included. Men principal investigators received significantly higher median funding per grant in 2011, 2012, and 2013; however, this trend reversed with women receiving nonsignificantly higher funding in 2015, 2017, 2018, 2021, and 2022. In 2020, women received significantly higher median funding per grant than men ($166,234 versus $121,384; p = 0.04). Throughout the 13-year period, men principal investigators accounted for approximately 71% of grants, with a very weak increasing trend in the percent of grants attributed to women (R 2 = 0.16; p < 0.001). Grants with men principal investigators resulted in more publications than those with women principal investigators (mean publications, 11.1 versus 6.6; p = 0.001). Publications resulting from grants awarded to men had a significantly higher mean RCR than those resulting from grants awarded to women (2.42 versus 2.09; p = 0.04).
There was no significant difference in the median amounts of funding per grant awarded to men and to women in 7 of the past 8 years, despite significantly greater funding per grant having been awarded to men from 2011 to 2013. Men principal investigators accounted for the majority of grants received during the study period, although this proportion was lower than the proportion of men among orthopaedic surgeons in 2022. This study could inform initiatives aimed at promoting equity in grant funding for orthopaedic research.
在许多学科中，研究资助方面的性别差距仍然存在。我们使用 Dimensions 数据库，旨在研究 2010 年以来美国骨科资助中的性别差距程度。我们的目的是提供对骨科研究领域性别差距程度的深入了解，并强调未来需要采取行动来解决这些差距。
使用与骨科相关的搜索词，我们查询了 2010 年至 2022 年期间授予的所有美国骨科研究资助。然后，手动筛选了 22326 个结果，以排除那些没有直接关注骨科研究的结果。每位主要研究者获得的金额以美元报告，并根据通货膨胀进行了调整。使用 Genderize.io 算法应用程序编程接口预测作者的性别。利用 iCite 相对引文比（RCR）评估与每项资助相关的出版物的影响力。
共纳入 1723 项资助。在 2011 年、2012 年和 2013 年，男性主要研究者获得的资助中位数显著更高；然而，这一趋势在 2015 年、2017 年、2018 年、2021 年和 2022 年发生逆转，女性获得的资助中位数非显著更高。2020 年，女性获得的资助中位数显著高于男性（166234 美元对 121384 美元；p = 0.04）。在这 13 年期间，男性主要研究者占资助的约 71%，女性所占比例呈微弱上升趋势（R 2 = 0.16；p < 0.001）。男性主要研究者的资助产生的出版物多于女性主要研究者的资助（平均出版物数量，11.1 篇对 6.6 篇；p = 0.001）。授予男性的资助产生的出版物的平均 RCR 显著高于授予女性的资助（2.42 对 2.09；p = 0.04）。
尽管从 2011 年至 2013 年，男性获得的资助中位数显著高于女性，但在过去 8 年中的 7 年中，男女获得的资助中位数没有显著差异。男性主要研究者在研究期间获得了大部分资助，但这一比例低于 2022 年骨科医生中男性的比例。本研究可为旨在促进骨科研究资助公平性的举措提供信息。
