Receiver Operating Characteristic (ROC) curve analysis evaluating the diagnostic performance of LINC00963 and SNHG15 in distinguishing CAD patients from healthy controls. (A) ROC analysis of LINC00963 expression yielded an area under the curve (AUC) of 0.9424 (95% CI: 0.8981–0.9867, P < 0.0001), indicating high diagnostic accuracy. (B) SNHG15 showed an AUC of 0.8196 (95% CI: 0.7374–0.9018, P < 0.0001), supporting its moderate diagnostic value.
