A Novel Integrated Score Index of Echocardiographic Indices for the Evaluation of Left Ventricular Diastolic Function
Fig 6
(A) Use of the integrated score index and predicted probability to discriminate any DHF in all the subjects (U.S. grades 1, 2, and 3). Integrated score index AUROC: 0.962 (blue line: integrated score index; green line: reference line). (B) The AUROC of the integrated score index used to predict any diastolic dysfunction (U.S. grades 1, 2, and 3) was 0.962, and the AUROC of the method suggested by the logistic regression was 0.970 (blue line: integrated score index; green line: logistic regression; yellow line: reference line).
