  2. aThe statistical association between two categorical variables was examined using the χ2 test.
  3. bThe statistical association between a categorical variable and a continuous variable was examined using Student's t-test.
  4. c“Admission delay” means that the time between hospital admission and ICU admission was not zero.
  5. d“Cared for by only one intensivist” means that the patient was cared for by only one intensivist during their ICU stay.
  6. eSee Additional file 4: Table S4 for the comparison of Elixhauser comorbidity measures between DNRCC-Arrest and non-DNR after propensity score matching.
  7. f“Floor” means that the patient was admitted to other departments before admitting to ICU.
