Abbreviations: AA, African American; CI, confidence interval; kg, kilogram; m, meter; max, maximum; min, minimum; N, number; NSAID, nonsteroidal anti-inflammatory; SSRI, selective serotonin reuptake inhibitor.

Biased corrected confidence intervals for sex differences in means for continuous variables were calculated from 50 000 bootstrap samples. Confidence intervals for sex differences in proportions were calculated according to Newcombe’s method.
