  1. ICU mortality: Hosmer and Lemeshow goodness-of-fit test Chi-squared = 5.16 (p = 0.23). This model has a 71% correct classification (57% for survivors and 81% for non-survivors)
  2. Neurological outcome: Hosmer and Lemeshow goodness-of-fit test Chi-squared = 9.18 (p = 0.33). This model has a 73% correct classification (48% for good neurological outcome and 82% for poor neurological outcome)
  3. CPR cardiopulmonary resuscitation
