  1. Selected variables are a predefined set of potential confounders including age, sex, initial shockable rhythm, bystander-witness status, CPR initiated by bystander, ROSC before hospital arrival, presumed cardiac etiology,
  2. time interval from EMS call to hospital arrival, therapeutic hypothermia, and oxy-Hb. The Hosmer-Lemeshow tests.
  3. were used to assess the goodness of fit of the model (P > 0.5).
  4. EMS, emergency medical service; OR, odds ratio; Oxy-Hb, oxyhemoglobin; ROSC, return of spontaneous circulation.
