Data are the sample sizes and corresponding column percentages, unless otherwise indicated. To compare characteristics by race, P values were calculated from Mann-Whitney tests and Fisher’s exact tests for continuous and categorical variables, respectively. Abbreviations: HCV, hepatitis C virus; HSV-2, herpes simplex virus type 2; BMI, body mass index; IQR, interquartile range.
