*The four cardiovascular disease risk factors analysed in this study were defined as follows: hypertension (systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg), hypercholesterolaemia (total cholesterol ≥240 mg/dl), high blood glucose (casual blood glucose ≥200 mg/dl) and smoking (current smoker).
†For each cardiovascular disease risk factor, the proportions (%) of participants who possess this risk factor are shown in each category.
