Fig. 1From: Evaluation of molecular signatures in the urinary bladder and upper tract urothelial carcinomas: a prospective controlled clinical studyReceiver operating characteristic (ROC) curves were performed to determine the area under the ROC curve (AUC), sensitivity, specificity, and p-value to determine the levels of the EGFR, Elk-1, and c-fos that best differentiate the UTUC versus the UBC. The optimal cutoff values were calculated as the marker level that maximizes the sensitivity and specificityBack to article page
