Purpose: The Canadian Network for Observational Drug Effect Studies (CNODES) studies the benefits and risks of post-market drugs and evaluates its research mobilization efforts for accountability, demonstrating value, and learning. As part of these evaluation efforts, and acknowledging gender disparity in authorship across many academic disciplines, CNODES examined the relationship between gender and authorship in its own journal articles and the literature citing them.
Methods: CNODES articles (published 2012-2017) and all citing articles were identified and extracted using Scopus. Scopus author IDs were used to extract full names and a web service (www.genderapi.com) was used to estimate gender, converting all probabilities <80% to "indeterminate." T-tests and visualizations were used to compare the proportion of females between CNODES and the citing literature.
Results: Twenty-eight CNODES articles and 463 citing articles were identified. The mean number of authors per article was 9.5 in CNODES articles and 5.7 in the citing literature. CNODES articles had a female authorship rate of 36%, compared to 29% in the citing literature (7% difference, 95% CI: [1%, 13%]). There were no female authors in 14% of CNODES articles versus 36% of the citing literature. Women were first authors in 25% and corresponding authors in 14% of CNODES articles.
Conclusions: This analysis provides a benchmark and method to monitor progress in female parity in pharmacoepidemiology authorship. Further work is needed to determine and address barriers and facilitators to women's recruitment and advancement in the field of pharmacoepidemiology.
