  1. Data are expressed as means (10%/25%/75%/90% percentiles). *P < 0.05, versus SIRS; P < 0.05, versus sepsis. APACHE, Acute Physiology and Chronic Health Evaluation; CRP, C-reactive protein; IL, interleukin; PCT, procalcitonin; SIRS, systemic inflammatory response syndrome; TNF, tumour necrosis factor.
