Multivariable logistic regression analysis was performed in 2 levels: (1) without adjustment (crude odds ratios (ORs) and 95% CI); (2) full adjustment, which is adjusted for obesity, Hb A1c, diabetes duration, GLDs usage, CKD, albuminuria, triglyceride and TC. GLD: glucose lowering drug; CKD: Chronic kidney disease; TC: total cholesterol; LDL-C: low density lipoprotein cholesterol; HDL-C: high density lipoprotein cholesterol; T2DM: Type 2 diabetes mellitus
