The AUCs of serum TG or RLP-C levels showed a correlation with the AUCs of plasma insulin (AUC-TG, r = 0.5437, P < 0.0001; AUC-RLC-P, r = 0.6847, P < 0.0001) (Fig. 2a, b), and furthermore, they correlated well with the insulin resistance index: (AUCs of insulin) × (AUCs of glucose) (AUC-TG, r = 0.7724, P < 0.0001; AUC-RLC-P, r = 0.7645, P < 0.0001) (Fig. 2c, d). Here, INS is linked to Insulin resistance.
