Figure 1From: Natriuretic peptide vs. clinical information for diagnosis of left ventricular systolic dysfunction in primary care Receiver-operator characteristic (ROC) curves for (a) NT-proBNP (AUC = 83%; 95 % CI = 75% to 92%) and (b) clinical risk score (AUC = 85%; 95 % CI = 79% to 91%) in the diagnosis of left ventricular systolic dysfunction confirmed by echocardiography in patients with preserved (n = 519) and impaired (n = 23) left ventricular function.
