From: Acoustic diagnosis of pulmonary hypertension: automated speech- recognition-inspired classification algorithm outperforms physicians

Figure 4

The receiver operating characteristic (ROC) curve for our algorithm to detect the presence or absence of PH.

The area-under-the-curve (AUC) was 0.74. The False Positive Rate (FPR)/True Positive Rate (TPR) point for the clinicians’ performance are also shown on the graph. The automated algorithm performs better than clinicians’ interpretation of the recorded heart sounds. X-axis shows the False Positive Rate, and the y-axis shows the True Positive Rate.
