One extreme outlier identified in the mild AUD severity category. When outlier was excluded, mean baseline alcohol use measures for those in the mild category (n=4) were as follows: Days of alcohol use (M=12; SD=12.3); Number of drinks per drinking day (M=3.2; SD=1); Number of heavy drinking days (M=3.5; SD=6.4); AUDIT (M=11; SD=6.4); Years of alcohol use (M=5.5; SD=4.7); SIP (M=6.5; SD=5).
