Model 1: adjusted for age, sex.

Model 2: further adjusted for education, current smoking, current drinking, physical activity, and body-mass index.

Model 3: further adjusted for fasting plasma glucose, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, estimated glomerular filtration rate, urinary albumin-to-creatine ratio.

Model 4: further adjusted for DBP (in association with SBP categories) or SBP (in association with DBP categories).

Ba-PWV, brachial-ankle pulse wave velocity; SBP, systolic blood pressure; DBP, diastolic blood pressure.
