Figure 4. The receiver operating characteristic (ROC) analysis evaluated the diagnostic performance of the three-microRNA panel. When combining miR-124-3p, let-7b-5p, and miR-221-3p, the area under the curve reached 0.833 (with 95%CI: 0.776-0.879), demonstrating 75.00% sensitivity and 77.68% specificity. In the visualization, a deep blue line depicts the actual ROC curve, while the lighter blue shading indicates the 95% confidence region, and a diagonal red line serves as the reference baseline. AUC: Area under curve; CI: confidence interval; miRNA: microRNAs
