Gender Disparity in the Citation of Surgical Research.

Abstract

Women surgeons face numerous barriers to career advancement. Inequitable citation of surgical literature may represent a contributing factor to gender disparities in academic surgery. This was a cross-sectional analysis of publications from 50 top-ranking surgery journals in 2017 and 2018, as defined by the 2019 InCites Journal Citation Reports. The citation rate of publications by women vs men first authors was compared. Similarly, the citation rate of publications by men vs women last authors was also compared. Adjusted regression analyses of citation rates accounted for the time interval since publication as well as the journal within which the article was published, among other potential confounding factors. A total of 19,084 publications from 48 surgery journals with a median (interquartile range) of 8 (4 to 15) citations contributing to a median (interquartile range) Journal Impact Factor of 4.0 (3.4 to 4.6) were analyzed. Compared with man-first author publications, woman-first author publications demonstrated a 9% lower citation rate (incidence rate ratio 0.91, p < 0.001). Similarly, compared with publications by man-last authors, woman-last author publications demonstrated a 4% lower citation rate (incidence rate ratio 0.96, p = 0.03). These associations persisted after multivariable adjustment for additional confounding factors, however, not on sensitivity analysis of 24 of the highest-ranking journals. Among top-tier surgical journals, publications by women-first and -last authors were less cited compared with publications by men-first and -last authors, but not among the highest-tier surgical journals. Gender bias may exist in the citation of surgical research, contributing to gender disparities in academic surgery.
