A) Example neonatal early EEG recording demonstrating broad, multifocal, excessive sharp transients. B) Example neonatal early EEG recording demonstrating consistent focal epileptiform discharges. C) Example fast epileptiform discharge (<100 ms) from an early neonatal EEG recording. D-F) Kaplan-Meier survival curves for D) Acute neonatal encephalopathy (blue), E) Suspicious clinical event (green), and F) Other high-risk indications (red) groups separated by the presence (dark) or absence (light) of epileptiform discharges on early EEG. G-I) Probability of future seizure separated by the presence (dark) or absence (light) of epileptiform discharges in the early EEG record, according to monitoring indication: G) Acute neonatal encephalopathy (blue) H) Suspicious clinical event (green) I) Other high-risk indications (red).
