Diagnostic accuracy and safety of endoscopic ultrasound-guided fine needle biopsy for evaluating mediastinal pathologies

Figure 1 Receiver operating characteristic curve illustrating the diagnostic performance of the endoscopic ultrasound-guided fine needle biopsy. The curve plots the true positive rate (sensitivity) against the false positive rate (1 - specificity). The area under the curve is 0.94 (95% confidence interval: 0.88-0.99), indicating excellent discriminatory ability of the procedure in distinguishing between malignant and benign cases. ROC: Receiver operating characteristic; AUC: Area under the curve.
