INS and metabolic syndrome: In the overall population, mean ± SDBMI (36.1 ± 5.7 vs. 27.1 ± 4.8 kg/m2, p < 0.001), WC (106.0 ± 13.1 vs. 83.8 ± 12.3 cm, p < 0.001), and insulin (15.1 ± 5.9 vs. 10.1 ± 5.4 IU/ml, p < 0.001), FBG (94.8 ± 10.3 vs. 91.6 ± 8.5 mg/dl, p = 0.049), and TG (159.6 ± 77.5 vs. 113.0 ± 41.3 mg/dl, p < 0.001) concentrations were significantly higher, while HDL-C concentrations (40.8 ± 10.8 vs. 49.7 ± 10.2 mg/dl, p < 0.001) were significantly lower among patients with MetS than in control subjects (Table 1).
