  1. aDifference between patients at therapeutic hypothermia (TH) centers and other hospitals is statistically significant at the 1 % level. All other differences are not statistically significant at the 5 % level
  2. bDifferences between patients at TH centers versus other hospitals were tested using Chi-square tests except for poverty rate in hospital service area where a t test was used
  3. cShockable rhythm was identified as ventricular fibrillation (VF), ventricular tachycardia (VT), or unknown AED shockable rhythm. Non-shockable rhythms were asystole and pulseless electrical activity
