Baseline characteristics of sample (N = 1200), grouped by intervention condition: Enhanced Intervention (EI, N = 544) vs. Standard Care (SC, N = 656).¹

1. No significant baseline differences. EI and SC compared using random effects regression models, controlling for clinic clustering. 2. Number of close friends/relatives: EI (median = 1, range = 0–15); SC (median = 1, range = 0–10); Total (median = 1, range = 0–15). Number of contacts with close friends/relatives, past month: EI (median = 22, range = 0–150); SC (median = 14.5, range = 0–262); Total (median = 17, range = 0–262).
