Fig. 1From: Prognostic value of heart failure echocardiography index in HF patients with preserved, mid-ranged and reduced ejection fractionReceiver operating characteristic (ROC) curves of heart failure echocardiography index (HFEI) and NT-proBNP for predicting adverse events within 1 year in patients with heart failure. The maximum area under the ROC curve of heart failure echocardiography index and NT-proBNP was 0.712 and 0.698, respectivelyBack to article page
