a
The 925/1775 does not precisely correspond with the 50.4% estimate presented in the main body as those data are weighted. The adjusted model includes all variables in the table and month of survey.
b
Increase is per SD of the sample = 17 years of age.
c
C2DE. AUDIT = Alcohol Use Disorders Identification Test. SD = standard deviation.
