ADIPOQ and type 2 diabetes mellitus: ROC curve analyses were performed to determine whether the Adipo/uACR ratio represent a superior marker for T2D than serum adiponectin concentration, and, indeed, the Adipo/uACR ratio (area under the ROC curve [AUC]: 0.7460, sensitivity: 0.6102, specificity: 0.7917, p < 0.001) was found to be superior to serum adiponectin concentration (AUC: 0.5785, sensitivity: 0.5367, specificity: 0.6073, p = 0.021) (p < 0.001 for the comparison) (Figure 2).
