ROC curves for the possible biomarkers to differentiate among thyroid carcinomas. For each molecule it is showed the ROC curve as well as the Area Under the Curve (AUC) value. The color code is the same than in Figure 8. A) curve for PTX3; B) COLEC12; C) PDGFRA. Those 3 genes were overexpressed in ATC meanwhile underexpressed in PTC. D) shows GPR110 ROC curve, which resulted overexpressed in PTC and underexpressed for ATC. Results are in full agreement with those in Figure 8.
