  1. Notes. RBT = Reinforcement Based Treatment. N = 124 (128–4 with no main sex partner) at baseline; for secondary outcomes, N = 96 (128–16 with no main sex partner and 16 failed to return for assessment) at post-treatment assessment, and N = 86 (128–27 with no main sex partner and 15 failed to return for assessment) at 3-month follow-up assessment, while for the primary outcome, N = 92 (128–16 with no main sex partner and 16 failed to return for assessment plus an additional 4 participants who had a main sex partner who declined to answer these two questions) at post-treatment assessment and N = 74 (128–27 with no main sex partner and 15 failed to return for assessment plus an additional 12 participants who had a main sex partner who declined to answer these two questions). Model-estimated means for the Poisson variable (past-30-day frequency of unprotected sexual intercourse) have been back-transformed into the metric of the original variables. Model-estimated means for the binomial variable (unprotected sex at the last encounter) are the predicted probabilities
