^aRelative likelihood of men physicians receiving payments compared with women physicians within each specialty group (odds ratio [OR]), as well as relative number of payments and percent difference of the value of payments between men and women within each specialty group (incident rate ratio [IRR] and percent difference, respectively). This multivariable analysis also adjusts for physician sex, specialty group, practice spending region, sole proprietorship, years of practice, and the interaction between physician sex and specialty.

^bReference group for each outcome is women physicians within each specialty group.
