Figure 1From: 20/(fasting C-peptide × fasting plasma glucose) is a simple and effective index of insulin resistance in patients with type 2 diabetes mellitus: a preliminary reportCorrelation between insulin resistance indices and GIR. Correlations between GIR and 20/(F-CPR × FPG) (A), HOMA-IR (B), ISI (C), BMI (D), waist circumstance (E), and adiponectin (F) were calculated by simple regression analysis. Black circles = patients with GIR 5–10 (mg·kg–1·min–1); white circles = patients with GIR < 5 or > 10 mg·kg–1·min–1.Back to article page
