Notes: GEE = generalized estimating equation; DID = difference-in-difference; AOR = adjusted odds ratio; CI = confidence interval.

^aAll models adjusted for age, ethnicity, sex, education, time-in-sample, and alcohol use;

^bseparate logistic models were estimated using GEE for each of the individual measures of warning label effectiveness.
