Gender and age distribution showed no statistical difference (P > 0.05) in two groups, whereas body mass index (BMI), fasting blood glucose (FBG), c peptide (C-P), fasting insulin (FINS), hemoglobin A1c (HbA1c), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC), and triglyceride (TG) differed significantly in the T2D group when compared with the healthy control group.
