Patterns of AUDIT-C and PEth by HIV and HCV status are shown in Figure 1. Among those who self-reported abstinence, the proportion with PEth ≥8 ng/mL was similar by HIV status (14.5% for HIV+; 15.0% for uninfected), but differed by HCV status; a higher proportion of those with HCV had PEth ≥8 ng/mL compared to those without HCV (18% vs. 11%, P=.009 for HIV+ and 21% vs. 13%, P=.039 for uninfected) (Figure 1a). Results were similar in the restricted sample, though not statistically significant. Among those who self-reported abstinence, a higher proportion of those with HCV had PEth ≥8 ng/mL compared to those without HCV (16% vs. 9% for HIV+ and 17% vs. 9% for uninfected) (Figure 1b).
