Prevalence ratios estimated using Poisson regression with robust variance estimation; Adjusted for HIV status, HBV status, alcohol frequency, age, marijuana use in the prior one month and injection drug use in the prior one month. HCV, hepatitis C virus; PR, prevalence ratio; 95% CI, 95% confidence interval; HIV, human immunodeficiency virus; HBV, hepatitis B virus
