  1. †Only significant variables are shown above. Model was adjusted for initial cohort of recruitment (p > 0.05) and all variables significant in unadjusted analyses: gender, sex-trade, DTES residence (all p > 0.05 after adjustment). *Data were time-updated semi-annually and behaviors refer to activities in the last six months.
