Sexual behavior changes after circumcision or learning that circumcision reduces transmission of HIV (N = 30)^*.

<p>*Categories are not mutually exclusive as two respondents reported multiple protective behaviors, therefore not all column totals add up to 100%.</p

*<p>The following co-variates were adjusted for: age, marital status, education, and income.</p>†<p>All odds ratios are population averaged, subject-specific not shown.</p

Baseline Comparability of Men in Circumcised and Uncircumcised Group (n = 1309)^*

*<p>16 men in “circumcised” group did not actually receive circumcisions and 3 men in the “uncircumcised” group received circumcisions.</p>**<p>Percentages do not add up to 100 because of rounding.</p
