Figure 2

Upper panel: Example item from the drug subscale of the HIV Risk Behavior Scale in HCV-positive (N=322) and HCV-negative (N=96) participants at screening (week 0) and during treatment. Data are shown only for occasions when participants had reported injecting (item 1; drug risk subscale). Possible item responses ranged from 0 (“I didn’t re-use needles in the last 2 weeks”) to 5 (“Never”).

Lower panel: Example item from the sex subscale of the HIV Risk Behavior Scale in HCV-positive (N=265) and HCV-negative (N=215) participants at screening (week 0) and during treatment. Data are shown only for occasions when participants had reported sexual activity (item 7; sex risk subscale). Possible item responses ranged from 0 (“I haven’t had any casual partners in the last 2 weeks”) to 5 (“Never”).
