aThe mean follow-up time was 5.4 years. Estimated by Cox regression analyses with imputed values for missing data and weighted by non-response weights. The number of cases reported is the mean of 20 imputed datasets not weighted by non-response weights.

bAdjusted for age and sex.

cAdjusted for age, sex, education, physical activity level in leisure time, smoking habits, body mass index, alcohol consumption, diabetes, and hypertension.
