Fig 1 ROC curve for ability of NT-proBNP to predict perioperative adverse cardiac events. Sensitivity and 1-specificity are plotted for various NT-proBNP. An NT-proBNP of ≥3984 ng litre−1 had a sensitivity of 69% and a specificity of 71%, likelihood ratio 2.27. The area under the ROC curve was 0.78 (95% CI 0.66–0.87).
