1. CI: confidence interval; OR: odds ratios; TC: total cholesterol; TG: triglyceride; HDL-c: high-density lipoprotein cholesterol; LDL-c: low-density lipoprotein cholesterol. Odds ratios plus confidence intervals based on simple and multiple logistic regression. The covariates in the comprehensive model were age, gender, ethnic, obese status (overweight/obesity), cigarette smoking, alcohol intake, plasma total cholesterol, triglyceride, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol.
