ROC curves comparing inflammatory markers discriminating abilities between sepsis and severe 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 sepsis and severe sepsis (P < 0.01).
