Contingency Table of EEG Reactivity and Outcome

	Poor Outcome, CPC 3–5	Good Outcome, CPC = 1–2
A
Unreactive EEG	51	14
Reactive EEG	19	65
B
Unreactive EEG	44	14
Reactive EEG	13	65
C
Unreactive EEG	48	9
Reactive EEG	22	70

Outcome was determined by the CPC scale (CPC) and dichotomized as good (CPC = 1–2) and poor (CPC = 3–5) outcome. EEG reactivity was based on majority vote (A), based on majority vote with patients dying of a non‐neurological cause excluded (B), and based on consensus meeting results (C).

CPC = Cerebral Performance Category; EEG = electroencephalographic.
