For all comparisons, referent category is listed last.
Education level, marital status, depression score using the Centers for Epidemiologic Studies symptom checklist score, cancer status, and hepatitis C serostatus were evaluated, but were excluded because they did not improve the final models.
Estimates and confidence intervals were multiplied by 100 to better visualize their relative magnitude.
Age regression coefficient and confidence interval are reported for an increased of every 10 years (decade).
Includes injection drug use, heroin, cocaine, crack, or methadone amphetamine use.
