BMI: body mass index; SBP: systolic blood pressure; DBP: diastolic blood pressure; FBG: fasting blood glucose; TG: triglycerides; TC: total cholesterol; LDL-C: low-density lipoprotein cholesterol; HDL-C: high-density lipoprotein cholesterol; CRP: C reactive protein. Data are expressed as a percent for categorical variables, as mean ± standard deviation for continuous variables in cases of normally distributed data, and as medians (interquartile ranges) otherwise. values for the difference between two groups.
