RR relative risk, aRR adjusted relative risk, CI confidence interval.

¹Following disclosure of first sex, participants were asked about sexual behaviors including new partners and condom use. The unadjusted models for new partners and condom use are thus reported among these post-disclosure visits only.

²Adjusted for time-fixed covariates (years between age of menarche and first sex) and time-varying covariates (age at study visit, bacterial vaginosis at visit, sex not self-reported but evident from other measures, new sexual partner, and reporting sex without a condom).
