  1. Characteristics of the study population are shown. Intensive care unit (ICU) and hospital length of stay (LOS) are presented as median and interquartile ranges. Other data are presented as mean ± standard deviation.
  2. APACHE = Acute Physiology and Chronic Health Evaluation; EA = endotoxin activity.
