The second regression model, which included the gene expression levels of VAT ZAG as dependent variable and the presence of metabolic syndrome, waist circumference, weight, insulin, HOMA-IR, and iron levels as independent variables (R2 = 0.422, F = 9, p < 0.001), demonstrated that 42% of VAT ZAG gene expression levels could be explained by a negative effect of waist circumference (ß = −0.276, p = 0.049), metabolic syndrome (ß = −0.306, p = 0.022), and insulin levels (ß = −0.336, p = 0.018). The gene discussed is INS; the disease is metabolic syndrome.
