Hypothermia versus Normothermia after Out-of-Hospital Cardiac Arrest
Patient / Population Intervention / Exposure Comparison Outcome

Discussion & critique
Definitive: targeted normothermia (fever avoidance) is now the standard. Subgroup of in-hospital arrest not studied; shockable & non-shockable rhythms both included.
