  1. Model 1: adjusted for age and sex
  2. Model 2: adjusted for age, sex, BMI, smoking, early parental cardiovascular disease, exercise capacity measured in metabolic equivalents, self-reported elevated cholesterol and abnormal blood glucose
  3. Please see Table 1 and the Methods-section for the explanation for the blood pressure groups
  4. 1 Persons with low ABI separated as their own group
