The p-values and effect directions (in brackets, positive +, negative −) are presented, significant results are displayed in bold. Analyses were adjusted for age, sex, intracranial volume, educational attainment, and PHQ-9 sum score. HC, hippocampus; CA, cornu ammonis; DG, dentate gyrus; HATA, hippocampus–amygdala transition area. The sample was separated by median split (median = 50 years).
