ROC curves comparing inflammatory markers discriminating abilities between systemic inflammatory response syndrome and sepsis(P 2 0.01). Receiver-operating characteristic (ROC) curves comparing procalcitonin (pct), lipopolysaccharide-binding protein (lbp), C-reactive protein (crp), IL-6 (il6), white blood cell (wbc) and neutrophil (neutro) discriminating abilities between systemic inflammatory response syndrome (SIRS) (noninfected with SIRS) and sepsis (sepsis and severe sepsis) (P < 0.01).
