A) The first 24 hours of cEEG recording for all patients is shown. The x-axis shows hours of recording, and y-axis shows individual patients. The color codes represent different EA patterns.
B) A magnified view of the upper left corner is shown to demonstrate the hour-by-hour pattern type and burden in the first 3 hours.
EA: epileptiform activity; GPD: Generalized periodic discharges, GRDA: generalized rhythmic delta activity. LRDA: lateralized rhythmic delta activity, LPD: Lateralized periodic discharges.
