Co: continuity score. Cy: sleep-wake cycling score. LB: lower border amplitude score. B: narrow bandwidth score. T: total score. WMD: white matter damage. ICH: intracranial hemorrhage. P-value: compared aEEG scores with WMD and ICH using one-way ANOVA. *P < 0.05, compared with no and mild WMD using LSD-t test.
