NOTE: HIV-negative seroconcordant refers to partnerships in which the participant in HIV-negative and partner is perceived HIV-negative/unknown. Cohort HIV-positive serodiscordant refers to partnerships in which the participant is HIV-positive and the partner is perceived HIV-negative/unknown. Cohort HIV-negative serodiscordant refers to partnerships in which the participant is HIV-negative and the partner is known HIV-positive. SD = standard deviation; ICC = intraclass correlation coefficient; CAS = condomless anal sex; PrEP = pre-exposure prophylaxis.
