Note. CI = confidence interval; ICC = intraclass correlation coefficient. d is the effect size estimate in standard deviation units based on the mean difference or Cox transformation of the odds ratio.³¹ Intervention effect is average over the 6- and 12-month follow-up assessments.

^aEstimates are odds ratios (intervention vs health control) for all outcomes except proportion condom-protected vaginal intercourse where it is the mean difference (intervention—control).
