P values are calculated for contingency tables.
Based on one or both of the following: 1) no pupillary and corneal reflexes, and/or 2) bilaterally absent N20 potentials on somatosensory evoked potentials (SSEP)
Defined as two or more of the following, with earliest prognostication beginning at 72 hours: 1) myoclonic status epilepticus ≤ 48 hours after return of spontaneous circulation (ROSC), 2) high neuron specific enolase levels at 48–72 hours after ROSC, 3) unreactive burst-suppression or status epilepticus on EEG, 4) diffuse hypoxic-ischaemic brain injury on brain CT (≤ 24 hours after ROSC) or MRI (days 2–5)
