VMMC = voluntary medical male circumcision.
Data are presented as number (percentage). P values for study group comparisons are based on Pearson χ2 test. The total number of responses for each outcome differs slightly from the total number of participants in the study group depending on missing responses (missing, don't know, refuse to answer, and not applicable are grouped together).
Longitudinal analyses of outcomes are restricted to sexually active subjects at any follow-up visit, defined as subjects who reported having sexual intercourse in the past 6 months. All subjects were uncircumcised at baseline. Study group at baseline refers to participants' choice of enrolling in the VMMC or control group.
Crude associations with P values less than or equal to .10.
