INS and diabetes mellitus: A significant positive effect of early-phase insulin sensitivity was associated with the AUC of PG levels at 0–30 min only in patients with DM-NAFLD (Bate = 0.625, P = 0.001) and a negative effect of insulin secretion was associated with the AUC of PG levels at 30–120 min only in patients with T2DM only (Bate = -0.413, P = 0.036).
