Peer review for the Canadian Journal of Anesthesia in 2016 and 2017: a retrospective analysis by reviewer and author gender.

Despite 36.2% of the authors being women, only 22.9% of reviewers were women and they represented only 18% of the individual written reviews gathered. Our results are consistent with previous reports of underrepresentation of women as reviewers in various disciplines. Formal policies that promote increased gender diversity should be considered.
