As expected, SBP (140.1 versus 124.0 mmHg, P < 0.001, t-test), DBP (88.7 versus 78.8 mmHg, P < 0.001), serum TG (343.3 versus 145.7 mg/dL, P < 0.001), insulin levels (26.5 versus 12.0 μU/mL, P < 0.001), fasting plasma glucose (127.3 versus 97.7 mg/dL, P < 0.001), HOMA-IR (3.9 versus 1.3, P < 0.001), TyG index (9.7 versus 8.7, P < 0.001), and TG/HDL-C ratio (9.2 versus 3.2, P < 0.001) were also significantly higher in the group with MetS than those in the group without MetS, respectively. Here, INS is linked to metabolic syndrome.
