Unadjusted
Adjusted for age, sex, diabetes, smoking, country, aspirin, ethnicity, body mass index, statin use at baseline
Model 2 plus adjusted for within-individual mean systolic blood pressure from baseline to second annual visit
Model 3 plus adjusted for use of antihypertensive drugs at baseline
