Figure 2From: c-KIT receptor expression is strictly associated with the biological behaviour of thyroid nodulesROC analysis for c-KIT expression. The true positive rate (Sensitivity) is plotted in function of the false positive rate (100-Specificity) for different cut-off points. Each point on the ROC plot represents a sensitivity/specificity pair corresponding to a particular decision threshold. (AUC = 0.9, C.I 95% 0.79-.94; p = 0.001).Back to article page
