Table 4 Multivariable regression models assessing association of drug use and hazardous drinking with perceived access to care and barriers to care, stratified by HIV status

From: Perceived access and barriers to care among illicit drug users and hazardous drinkers: findings from the Seek, Test, Treat, and Retain data harmonization initiative (STTR)

  1. All models were adjusted for age, gender, and race/ethnicity
  2. aScores were based on summation of points from individual questions within each domain (perceived access to care: 6 questions; barriers to care: 7; social support: 5). The domain score ranges were: perceived access to care 5–30 points; barriers to care 0–7 points; social support 5–25 points
