Hepatitis B infection was defined by a positive hepatitis B surface antigen or detectable hepatitis B DNA result. Hepatitis C infection was defined as a positive hepatitis C antibody or detectable hepatitis C RNA or genotype result.
bThe subcohort is the group of randomly selected individuals from contributing cohorts, all of whom underwent comprehensive medical record review.
cMen who have sex with men who also reported injection drug use were classified as injection drug use risk.
