Figure 2

Receiver operating characteristic (ROC) curves of procalcitonin, presepsin, C-reactive protein, and qSOFA score for differentiating between patients with and without bacteremia. The ROC curve analysis showed the performance for predicting bacteremia: AUC of 0.80 (95% CI: 0.72–0.88) for procalcitonin, AUC of 0.69 (95% CI: 0.60–0.79) for presepsin, AUC of 0.60 (95% CI: 0.49–0.70) for C-reactive protein, and AUC of 0.64 (95% CI: 0.55–0.73) for qSOFA score. AUC, area under the curve; CI, confidence interval.
