  1. Hazard ratios are indicated per 1SD higher logPWV. Adjustment was performed for the following risk factors: model 1 = adjusted for age, gender, and race; model 2 = model 1 + mean blood pressure, antihypertensive medication use, diabetes, smoking, total cholesterol, HDL cholesterol, BMI.
  2. HR indicates hazard ratio; BMI, body mass index; HDL, high density lipoprotein; PWV, pulse wave velocity; logPWV, log-transformed PWV
