Receiver operating characteristic curves of the presepsin level, lactate level, and the SOFA score in predicting patients’ in-hospital mortality. Areas under the receiver operating characteristic (ROC) curves: the lactate level (blue line): 0.711 (95% confidence interval (CI): 0.622 to 0.800, P=0.000); the presepsin level (red line): 0.703 (95% CI: 0.614 to 0.793, P=0.000); the SOFA score (green line): 0.793 (95% CI: 0.716 to 0.870, P=0.000); the SOFA score + the presepsin level (purple line): 0.817 (95% CI: 0.742 to 0.892, P=0.000). The AUC value of a combination of the SOFA score and the presepsin level is significantly larger than that of the SOFA score alone in predicting patients’ in-hospital mortality from sepsis (AUC: 0.817 vs 0.793, P=0.041).
