  3. ‡APACHE II = Acute Physiology and Chronic Health Evaluation. Higher scores reflects more severe critical illness.
  4. §SOFA = Sequencial Organ Failure Assessment. Higher scores reflect more severe organic dysfunction. for the worst values in the six organs during the first 24 hours after enrollment.
