Fig. 1.
Linear correlations between surrogate indices of insulin sensitivity/resistance and reference glucose clamp method (SIClamp). The solid line represents the linear least-squares fit between each calculated surrogate index of insulin sensitivity/resistance and measured SIClamp. Correlation coefficients (r) and corresponding P values are shown in each part. A: results derived from quantitative insulin sensitivity check index (QUICKI). B: results derived from homeostasis model assessment 2 of insulin resistance (HOMA2-IR). C: results derived from fasting insulin-to-glucose ratio (FIGR). D: results derived from fasting insulin concentrations.
