The usefulness of contrast echocardiography in the evaluation of cardiac masses: a multicenter study

Table 3 Comparison of diagnostic performance in differentiating thrombus from cardiac tumor and Malignant tumor from benign tumor

		Sensitivity	Specificity	AUC	Accuracy	PPV	NPV
Thrombus/cardiac tumor	A1/A2 (Cutoff value = 0.499)	0.979 (90.92-99.8%)	0.884 (74.3-96.1%)	0.977 (0.947-1.000)	0.9568 (0.936–0.994)	0.959 (0.943–0.981)	0.951 (0.947-1.000)
Malignant tumor/benign tumor	A1/A2 (Cutoff value = 1.583)	0.933 (77.9-99.2%)	0.939 (85.2-98.3%)	0.950(0.894-1.000)	0.9375 (0.921–0.984)	0.875 (0.841–0.978)	0.969 (0.962-1.000)

AUC, the area under the receiver operating characteristic curve; NPV, negative predictive value; PPV, positive predictive value
