baPWV, brachial-ankle pulse wave velocity; SBP, systolic blood pressure; OR, odds ratio; CI, confidence interval. Model 1, adjusted for age, sex, and baseline SBP; Model 2, adjusted for variables in model 1 and body mass index, current smoking, current drinking, baseline estimated glomerular filtration rate, diabetes mellitus, dyslipidemia, history of cardiovascular disease, hypoglycemic agents, and lipid-lowering agents.
