The recall period for all sexual behaviors was “since last visit.” Most visits (93.1%) were approximately 6 months prior, 5.0% were approximately 12 months prior, and 1.9% longer than 12 months prior. Consistent condom use refers to reporting “always” using condoms during AI or VI, since last visit. VI was reported at all visits when AI was reported.

AI = anal intercourse; VI = vaginal intercourse; 95% CI = 95% confidence interval (calculated using the Clopper-Pearson confidence interval for a binomial proportion).
