Estimated probabilities of regular HIV care (a significant interaction) and past-year drug treatment (b significant interaction) based on internalized HIV stigma and internalized drug stigma interaction models, statistically adjusting for sociodemographic characteristics (age, gender, education, and financial status) and social/behavioral history (frequency of injection drug use, time since first use, and time since HIV diagnosis). Stigma variables and covariates (dummy coded as needed) were mean-centered prior to analyses. High and low drug stigma values represent mean value ± 1 standard deviation
