Estimates of the Association between State-level HIV Pre-Test Counseling Policies and Availability of Hepatitis C Testing Services On-site in Opioid Treatment Programs, by Type of Drug Treatment Program. Notes: the figures presented here refer to OTPs, which offer at least some kind of HCV testing services (i.e., on-site or offsite). The figures reported are predicted probabilities obtained from logistic regressions with state fixed-effects. The analytical sample in these models includes all OTPs in states where the HIV-relation legislation changed between 2005 and 2011. Error bars represent 95 % confidence intervals. In this model, there was no significant interaction between type of treatment program and adoption of legislation consistent with CDC guidelines. Standard errors are adjusted for clustering of observations within state
