CVD, cardiovascular diseases; non‐HDL cholesterol, non‐high‐density‐lipoprotein cholesterol; OR, odds ratio.
Mean differences were adjusted for baseline age, body mass index, systolic blood pressure, non‐HDL cholesterol, smoking status, alcohol drinking, and medication uses for diabetes mellitus, hypertension, and dyslipidemia by multiple regression analyses.
ORs were adjusted for baseline age, body mass index, systolic blood pressure, non‐HDL cholesterol, smoking status, alcohol drinking, and medication uses for diabetes mellitus, hypertension, and dyslipidemia by multinomial logistic regression analyses.
