The pathogenesis, epidemiology, and outcomes for hypertension, obesity, and diabetes differ in women and men and in boys and girls, demonstrating the intersection of sex and gender. However, because of a lack of specifically designed studies to examine therapeutic sexspecific responses to therapy, we lack a robust evidence base to present well-defended sex-specific guidance. Future studies should address sex and gender as outcome variables incorporated into the design of the study. Currently available data from completed and in-process studies should be explored for sex differences. RCT = randomized controlled trial; rx = treatment.
