Notes: No. = number; b = unstandardized estimate; SE = standard errors; p = p value; var. = random effects variance; χ² = chi-square test. Heavy drinking days were defined as four or more standard drinks for women and five or more standard drinks for men (National Institute on Alcohol Abuse and Alcoholism, 2004).
