Figure 1. Total HIV Risk Behaviors and Subscale Risk Behaviors.

Figure 1

Total HIV risk behavior scores (top panel), drug risk behavior scores (middle panel) and sex risk behavior scores (bottom panel) from the HIV Risk Behavior Scale in HCV-positive (N=356) and HCV-negative (N=291) participants at screening (week 0) and during treatment. Asterisk indicates weeks at which total score for HCV-positive and HCV-negative participants were significantly different (p<.05). Higher scores indicate greater frequency of risky behaviors.
