  1. *OR, odds ratio, represented the effect for every 10 cm/s increase of ba-PWV. Adjusted for age, sex, hypertension, dyslipidemia, diabetes mellitus, tobacco intake, alcohol intake, BMI, SCR, anti-hypertensive medicine, lipid-lowering medicine, anti-diabetic medicine and self-reported CVD history.
