Comparison of clinical characteristics and glucose, cortisol, and insulin indices of three ICU groups: survivors without sepsis (Group 1), survivors with sepsis (Group 2) and non-survivors (Group 3).

Data are numbers (%) or medians [interquartile range]. APACHE = Acute Physiology and Chronic Health Evaluation; ICU = Intensive Care Unit, IU = International Units.1P12 value was determined with the use of Mann-Whitney U-test between survivors without sepsis and survivors with sepsis.2P23 value was determined with the use of Mann-Whitney U-test between survivors with sepsis and non-survivors.3To convert the values for glucose from mmol/l to mg/dl, multiply by 18.018.4During the whole ICU stay.5One day before a date when sepsis was identified.6One day before death.
