The data on the left is unadjusted, and the data on the right is adjusted. P < 0.05 were considered statistically significant. All models were adjusted for age, sex, BMI, fasting blood glucose, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides concentration, albumin, and creatinine.

Data with P<0.05 are marked in bold for clarity.
