Trends of women's authorship in an Iranian medical journal from 1999 to 2019

Author's gender is a potential factor in scientific publications. We evaluated the trends of authorship gender by focusing on women in an Iranian medical journal and followed two aims: A) Mapping gender trends in authorship positions; B) Drawing the patterns among authors. Our results showed that between 1999 and 2019, the role of women as first author was 26.7% and 54.9% (p < 0.05); as last authors 33.3% and 37.3% and as corresponding author 23.3% and 36.7%, respectively. Despite progresses made by women, they were not significantly successful as corresponding and last authors. Further researchers around the world can have similar focus and be useful in making decisions for equality issues.
