All analyses were stratified by date of enrolment (tertiles).

Model 1a: adjusted for length of follow-up (i.e. baseline age).

Model 1b: model 1a plus alcohol intake, alcohol abstinence, physical activity, smoking and education.

Model 2: model 1b plus baseline BMI, waist circumference, hypertension, hypercholesterolaemia and diabetes.

^*Test for trend was performed by including the categorised index as a linear variable in the model.
