The ROC analysis for the onset of T2D showed that the optimal cut‐off point for adiponectin was 6.4 μ g/mL (AUC = 0.859), while the optimal cut‐off points for ALT, the AST/ALT ratio and VAT were 35 IU/L (AUC = 0.821), 0.85 (AUC = 0.794) and 78 cm2 (AUC = 0.713) (Figure 2). This evidence concerns the gene ADIPOQ and type 2 diabetes mellitus.
