EEG monitoring commenced as soon as possible after birth, using disposable electrodes according to the 10:20 electrode placement system for neonates (F3, F4, C3, C4, Cz, T3, T4, O1/P3 and O2/P4). EEG recording sampling rate was 250 Hz or 256 Hz and filter bandwidth was 0.5 to 70 Hz. Separate electrodes on each shoulder of the newborn were used for single channel ECG monitoring synchronised with EEG. The EEG machines used were: NicoletOne ICU Monitor (Natus, United States), Nihon Kohden EEG (Neurofax EEG-1200, Japan) or XLTek EEG (Natus, United States).
The earliest one-hour epoch of EEG-ECG was extracted for each infant, within 12 h of age.

All infants underwent prolonged video cEEG monitoring as clinically indicated, using a 10:20 EEG electrode modified neonatal system with disposable electrodes placed at F3, F4, C3, C4, Cz, T3, T4, O1/P3, and O2/P4. Three different EEG machines were used for monitoring: Neurofax EEG-1200 (Nihon Kohden), NicoletOne ICU Monitor (Natus), and XLTek EEG (Natus). Teams at each site were trained in EEG electrode application and maintenance of good quality recordings. The clinical teams at each site had the aEEG signals from F3-C3 and F4-C4, 8 raw EEG channels, and electrocardiography and respiratory traces displayed on the EEG monitors and available to review. No standard EEG review protocol was imposed during the study period, and the clinical teams reviewed the monitoring data as recommended by the local guidelines.
