  1. Diagnosis of SIRS (N = 130) was by consensus RPD. Parameters are listed on the basis of decreasing significance (two-tailed p value) as evaluated either by t test (for continuous variables) or by a two-proportions z-test (www.vassarstats.net) for categorical variables
  2. Abbreviations: Glucose.Max maximum blood glucose concentration, HR.Max maximum heart rate, HR.Min minimum heart rate, ICU LoS length of stay in ICU (days), MAP.Max maximum mean arterial blood pressure, MAP.Min minimum mean arterial blood pressure, N.SIRS number of SIRS criteria met, Temp.Max maximum core temperature, Temp.Min minimum core temperature, WBC.Max maximum white blood cell count, WBC.Min minimum white blood cell count
