*Row percentages displayed for drinking categories calculated only within those with information on alcohol consumption (n=1 104 838; 57% of overall sample). In imputed data, drinking category proportions are as follows: 14.7% non-drinkers, 3.2% former drinkers, 11.6% occasional drinkers, 62.4% moderate drinkers, and 8.1% heavy drinkers. Proportion of participants with non-missing values of covariates: smoking 73.0% (1 413 749 participants), systolic blood pressure 73.2% (1 418 578 participants), BMI 30.6% (592 127 participants), and HDLC 5.5% (107 080 participants). All other covariates have 100% coverage.
