Analyses based on aggregate sample (N=10,652), except where otherwise indicated, and include enrollment site as a covariate.
SUD identification based on substance-specific diagnostic thresholds from the AUDIT-C (alcohol UD) and the ASSIST (cocaine UD, marijuana UD, methamphetamine UD, opioid UD).
Odds-ratios reflect the likelihood of SUD relative to the reference category
