Model 1 unadjusted. Model 2 adjusted for age, gender, body mass index, cigarette smoking history, alcohol consumption history, hypertension, hyperlipidemia, and CHD. Model 3 adjusted for age, gender, body mass index, cigarette smoking history, alcohol consumption history, hypertension, hyperlipidemia, coronary heart disease, systolic blood pressure, diastolic blood pressure fasting blood glucose, glycated hemoglobin, total cholesterol, triglycerides, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol, aspartate aminotransferase, alanine aminotransferase, uric acid, C-reactive protein, white blood cell count, and estimated glomerular filtration rate. RBP: Retinol-binding protein; OR: Odds ratio; CI: Confidence interval.
