Changes in Key HIV-Risk Behaviors Across Visits Ofthe 1,569participants remaining in the studyin October 2013, 91 % completed the 12-month visit, 68 % completed the 24month visit, and 48 %completed the 36-month visit. For numbers of visits, 164/1569 (10 %) came for only 2 visits (enrollment and any other one follow-up visit), and 183/1569 (12 %) came for only 3 visits (enrollment and any other two follow-up visits). We examined changes in key HIV-risk behaviors from the baseline to the 36-month visit (Fig. 1). Asimilar pattern of decreasing risk was observed for all three HIV-risk behaviors. The proportion of participants who reported any UAI was 56 % at baseline, and decreased to 19 % by the 36-month visit.
