Fig. 4From: Computed tomography and magnetic resonance imaging evaluation of pelvic lymph node metastasis in bladder cancerReceiving operating characteristic (ROC) curve of short-axis diameter of metastatic lymph nodes measured on CT and/or MRI (the blue line). A cutoff value of 6.8 mm results in optimal sensitivity (83.0%) and specificity (64.3%) and high Youden index (47.3%). The area under the ROC curve (AUC) is 0.815, and 95% confidence interval is 0.708–0.895Back to article page
