A p value of less than 0.05 was considered statistically significant and the corresponding results are shown in italics

ROI region of interest, CHI cognitively healthy adults, HV hippocampal volume

Basic adjusted model was adjusted for age, gender (female as reference), education, and total intracranial volume

Fully adjusted model was adjusted for the same variables in basic adjusted model, as well as memory performance
