Table excludes individuals with prior chronic disease at recruitment (ie, ischemic heart disease, stroke, chronic kidney disease, cirrhosis, cancer, or emphysema), missing or out-of-range data on any analysis covariate (ie, sex, district of residence, educational level attained, anthropometry, smoking status, alcohol intake, leisure time physical activity, or diabetes status), uncertain follow-up, or missing or out-of-range blood pressure (defined as SBP <80 or >250 mm Hg, DBP <40 or >150 mm Hg, or pulse pressure <15 mm Hg).
