*For each participant, prevalent concurrency at each interview was defined by an overlap in reported sexual partnership dates during the recall period preceding the interview.
†Incident concurrency was defined as overlap in sexual partnership dates for participants, among those with no overlap during the recall period preceding the previous interview.
‡Denominators for prevalence are all participants interviewed about the preceding recall period. Denominators for incidence are participants who were not concurrent during the recall period preceding the previous interview.
