1For descriptive purposes, AUDIT hazardous alcohol use total scores are grouped here according to categories of increasing alcohol risk from medium level (scores 8–15), high level (scores 16–19), to indication for alcohol dependence (scores of 20 and above)19.
Note: In line with the CONSORT 2010 guidelines, no test of significance of baseline differences between intervention groups were conducted for the covariates; however, the data were examined to identify any large differences between groups at baseline.
