ROC analysis for KIT, TC1, miR-146b, miR-222 for case classification into malignant vs benign. KIT and miRNA146b showed the highest discriminating power (AUC = 0.9). The true positive rate (sensitivity) is plotted as a function of the false positive rate (100-specificity) for different cutoff points. Each point on the ROC plot represents a sensitivity/specificity pair corresponding to a particular decision threshold
