Notes:

^*ART initiation refers to the first follow-up completed at least 6 months following the date of therapy initiation; a Odds Ratio; b Adjusted Odds Ratio; c MMT = current enrollment in methadone maintenance therapy;

^†Refers to injecting ≥ daily during the past 6-month period prior to the interview.
