PurposeThis study analyzed sex differences among cornea specialists with regards to academic rank, scholarly productivity, National Institutes of Health (NIH) funding, and industry partnerships.DesignCross-sectional study.MethodsThis was a study of faculty at 113 US academic programs. Sex, residency graduation year, and academic rank were collected from institutional websites between January and March 2019. H-indices and m-quotients were collected from the Scopus database. The NIH Research Portfolio Online Reporting Tool and Centers for Medicare and Medicaid Services databases were queried for data on NIH funding and industry partnerships.ResultsOf the 440 cornea specialists identified, 131 (29.8%) were female. The proportions of females and males at each academic rank (assistant 69.5% vs 41.8%; associate 17.6% vs 21.0%; full professor 13.0% vs 37.2%) were not significant after adjusting for career duration (P = .083, .459, and .113, respectively). Females had significantly lower median h-indices (4.0 [interquartile range {IQR} 7.0] vs 11.0 [IQR 17.0], P < .001) and shorter median career duration (12.0 [IQR 11.0] vs. 25.0 [IQR 20.0] years, P < .001) than males but similar median m-quotients (0.5 [IQR 0.8] vs 0.5 [IQR 0.8], P = 1.00). Sex differences in h-indices were not seen at each academic rank or career duration interval. Among NIH-funded investigators, the median grant funding was $1.6M (IQR $2.2M) for females and $1.2M (IQR $4.6M, P = .853) for males. Overall, 25.5% of females and 58.6% of males (P = .600) had industry partnerships.ConclusionSex differences within academic ranks and h-indices are likely due to a smaller proportion of females with advanced career duration.Copyright © 2020 Elsevier Inc.
