Figure 1 Receiver operating characteristic (ROC) curve of brain natriuretic peptide (BNP) in ruling out diastolic dysfunction. Area under the curve = 0.86, SE = 0.08. P value = 0.003, 95% confidence interval (CI) = 0.71-1.01. At cutoff point 28.5, sensitivity = 88.9%, specificity = 81.2%, positive predictive value = 72.7, negative predictive value = 92.9%.
