^aA generalized linear model was carried out with intracranial volume as the covariate, median (25–75th percentile) was used for statistical description; ^ba general linear model was carried out with intracranial volume as the covariate, and was used for statistical description. HATA: hippocampal amygdala transition area; GC-ML-DG: molecular layer of the dentate gyrus. The unit of volume is cubic millimeters.
