Evaluation of Procalcitonin, C-Reactive Protein, and Interleukin-6 as Early Markers for Diagnosis of Neonatal Sepsis

Figure 2

Receiver operating characteristics (ROC) curves for the studied sepsis markers: (a) ROC curve for PCT: AUC: 0.991, value ≤0.001. (b) ROC curve for CRP: AUC: 0.841, value = 0.001 (c) ROC curve for IL-6: AUC: 0.801, value = 0.005. PCT: procalcitonin, CRP: C-reactive protein, IL-6: interleukin 6, PPV: positive predictive value, NPV: negative predictive value, and AUC: area under the curve. Diagonal segments are produced by ties.
