INS and Insulin resistance: As expected, the TyG index also showed significant correlations with FPG levels (r = 0.243; P<0.0001), fasting insulin levels (r = 0.249; P<0.0001), HOMA-IR (r = 0.273; P<0.0001), and HOMA-ß (r = 0.143; P<0.0001) indicating that this index could reflect the degree of insulin resistance and compensatory ß-cell function in these study subjects.
