Trends in women's representation as lead authors in high impact journals of lung cancer.

Background: Women's participation in the clinical oncology practice has increased over the past decade. There is a need to investigate whether women's participation in academia, as reflected by publication activity, increased over the time. This study aimed to investigate trends in female authorship in top journals of lung cancer in the past ten years. Methods: In this cross-sectional study of all original research and review articles published in lung cancer journals including Results: A total of 3,625 first authors and 3,612 corresponding authors were identified in the journals during the years studied. The sex of the author was revealed for 98.5%. Among 3,625 first authors with the sex being revealed, 1,224 (33.7%) were women. The proportion of female first authors increased remarkably from 29.4% in 2012 to 39.8% in 2021. The annual percentage change (APC) in female first authorship took place in 2019 [APC for 2019-2021, 37.03, 95% confidence interval (CI): 18.0-59.1, P=0.003]. The proportion of first authors in Conclusions: The sex gap in the first authorship of lung cancer research articles has improved markedly in the recent years, however, sex imparities persist especially in corresponding authorship. There is an urgent need to proactively support and promote women in taking the leadership roles, thereby increasing their contributions to and influence on the development or advancement for future healthcare policies and practices.
