Probability (95% CI) of Having HIV-1 RNA Detected in the Genital Tract over All Visits and Stratified When Plasma Viral Load Was Detectable and Undetectable, and the Between-Subject and Within-Subject Odds Ratios of Having Genital Tract Shedding When Plasma Viral Load is Detectable Versus Undetectable, at Visits ≥30 Days after Changing Highly Active Antiretroviral Therapy Regimens

^{^a}

Between-subject or cross-sectional effect: ratio of the odds of GT shedding when PVL>80 versus PVL ≤80 for women with PVL ≤80 at baseline compared to women with PVL>80 at baseline.

^{^b}

Within-subject or longitudinal effect: odds ratio of GT shedding for women who transition from PVL ≤80 at baseline to PVL>80 at follow-up.

^{^c}

Model adjusted for baseline CD4, change in CD4, baseline BV, change in BV from baseline.

^{^d}

Model adjusted for baseline CD4, change in CD4, baseline BV, change in BV from baseline, and hysterectomy status (yes/no).

OR, odds ratio; BV, bacterial vaginosis.
