Comparison of mean PLI values between the AESD and PFS groups. (a) Mean PLI values for all electrode pairs by frequency band and (b) mean PLI values for electrode pairs across different frequency bands, with coloring indicating electrode pairs for which mean PLI values significantly differed between the AESD and PFS groups. The AESD group exhibited significantly higher mean PLI values across all frequency bands. In the delta frequency band, the mean PLI values between the frontal pole and occipital regions were significantly higher in the AESD group compared with the PFS group. In the gamma frequency band, mean PLI values between the hemispheres were significantly higher in the AESD group than in the PFS group. AESD, acute encephalopathy with biphasic seizures and late reduced diffusion; PFS, prolonged febrile seizure; PLI, phase lag index.
