Fig. 1From: Use of speckle-tracking echocardiography–derived strain and systolic strain rate measurements to predict rejection in transplant hearts with preserved ejection fractionGlobal Circumferential Strain Area Under the Receiver Operating Characteristic Curve. With values less negative than a cutoff of − 17.60%, the sensitivity and specificity of GCS to detect severe acute rejection were 81.8 and 68.4%, respectively. Area under the curve (AUC) of the receiver operating characteristic analysis for global circumferential strain is 0.77 (P < .001)Back to article page
