Abbreviations: CI, confidence interval; HR, hazard ratio.

^a Binge-drinking frequency was dichotomized into frequent (heavy episodic drinking; ≥60.00 g of alcohol per occasion at least once per month) and never or infrequent (≥60.00 g of alcohol per occasion less frequently than once per month).

^b Participants with average alcohol intake < 2.00 g/day were not included in the analyses.

^c HRs and 95% CIs were derived from Cox models that were adjusted for age and sex.

^d HRs and 95% CIs were derived from Cox models that were adjusted for age, sex, education, marital status, smoking, physical activity, body mass index, and familial history of coronary heart disease.

^e HRs and 95% CIs were derived from Cox models that were adjusted for age, sex, education, marital status, smoking, physical activity, body mass index, familial history of coronary heart disease, and the average quantity of alcohol consumed.
