Figure 1

Receiver operating characteristic (ROC) curve for N-terminal-pro-B-type natriuretic peptide (NT-proBNP) in the entire cohort of critically ill patients. The ROC curve depicts the relationship between the proportion of true positives (Sensitivity) and the proportion of false positives (1 – Specificity) of different thresholds of NT-proBNP concentrations when tested to predict cardiac dysfunction. Diagonal segments are produced by ties. The area under the ROC curve was 0.76 (95% confidence interval 0.69 to 0.83).
