  1. AUC denotes area under the curve . An AUC value > 0.8 is considered good, a range between 0.60-0.80 is considered as moderate, and an AUC value < 0.60 is regarded as poor.
  2. ASA, American society of anesthesiologists (ASA) score.
  3. APACHE II denotes Acute physiology and chronic health evaluation II.
  4. Modified APACHE II, APACHE II calculated when no available blood gas.
  5. SAPS, Simplified acute physiology score II (SAPS II).
  6. MPM, Mortality probability models II (MPM II).
  7. MPI denotes Mannheim peritonitis index.
  8. Modified MPI, MPI calculated when no available blood gas.
