Clinical risk factors for model adjustment included: diabetes, body mass index, systolic blood pressure, total cholesterol, high‐density lipoprotein cholesterol, cigarettes per day at year 7, lifetime pack‐years smoking history up to year 7, CARDIA physical activity at year 7. CARDIA indicates Coronary Artery Risk Development in Young Adults study; CVH, cardiovascular health score; and HR, hazard ratio.
