IL6 and metabolic syndrome: Specifically, the concentrations of cytokines in SZ-MetS versus HCs were as follows: such as IL-1β (3.14 ± 3.03 pg/mL vs. 0.94 ± 0.31 pg/mL), IL-1ra (650.79 ± 546.49 pg/mL vs. 246.95 ± 125.22 pg/mL), IL-4 (3.84 ± 2.08 pg/mL vs. 2.59 ± 0.8 pg/mL), IL-5 (68.69 ± 45.93 pg/mL vs. 27.1 ± 25.94 pg/mL), IL-6 (12.07 ± 10.07 pg/mL vs. 4.18 ± 2.07 pg/mL), IL-8 (111.94 ± 162.57 pg/mL vs. 10.26 ± 6.77 pg/mL), IL-17 (35.36 ± 14.78 pg/mL vs. 28.03 ± 6.69 pg/mL), and IFN-γ (8.89 ± 4.13 pg/mL vs. 6.25 ± 1.36 pg/mL).
