Figure 1

Receiver operating characteristic (ROC) curves (95% confidence interval) for the prediction of sepsis versus systemic inflammatory response syndrome. C-reactive protein (CRP) (thin dashed line), 0.794 (0.644–0.944) (standard error, 0.05; P < 0.05); best cut-off, 90 mg/l; sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV), 74, 85, 92, and 53. Procalcitonin (PCT) (thick solid line), 0.731 (0.587–0.875) (standard error, 0.05; P < 0.05); best cut-off, 1.2 ng/ml; sensitivity, specificity, NPV, and PPV, 63, 87, 92, and 51. Sepsis score (thin solid line), 0.701 (0.534–0.869) (standard error, 0.08; P = 0.055). Sequential organ failure assessment score (thick dashed line), 0.505 (0.299–0.711) (standard error, 0.105; P = 0.96).
