Body mass index (BMI), waist-hip ratio (WHR), fasting plasma glucose (FPG), plasma glucose 2 hours after oral glucose challenge (2HPG), triglyceride (TG), fasting insulin (FINS) concentration, 2-hour insulin (2HINS) concentration, insulin resistance index (IR), and C-reactive protein (CRP) values were all significantly higher in the T2DM group than in the NGT group (P<0.05). Here, CRP is linked to type 2 diabetes mellitus.
