ENO2 and Bilateral tonic-clonic seizure: An NSE level ≥ 97 ng/mL (n = 35), myoclonus at 24 h (n = 26), and absence of pupillary light reflex (n = 18) or corneal reflex (n = 31), tonic-clonic seizures (n = 6) and malignant EEG pattern at 72 h (n = 32) were predictive for a poor outcome with no false positives.
