aMultiple linear regression analysis was performed after controlling for the following dummy variables: gender (ref. male), education level (ref. primary and below), marital status (ref. married), having children (ref, yes), employment status (ref. unemployed), average monthly income over the past year (Chinese yuan, ref. <1000), stable income sources (ref. yes), living with family (ref. yes), chronic disease (ref. yes), and drug use over the past month (ref. yes), as well as the continuous characteristics (age, initial drug use age, days of receiving MMT, and average daily methadone dose)
