^aSignificance is calculated in differences across four participant types at baseline assessment.

^bCalculated as percent of participants who injected at baseline as follows: PHA=46; CR=73; untrained PHA=35; CR of untrained PHA=51, total sample=205.

^cCalculated as percent of participants who smoked crack at baseline as follows: PHA=76; CR=136; untrained PHA=41; CR of untrained PHA=59, total sample=312.

^dCalculated as percent of participants who had any unprotected sex at baseline as follows: PHA=110; CR=219; untrained PHA=64; CR of untrained PHS=124, total sample=517.

^eMean score on a 15-item Likert scale, with responses ranging from 1 = strongly disagree to 4 = strongly agree. Negative items were reverse coded for analysis.
