Fig. 3From: Hormone replacement therapy is associated with improved cognition and larger brain volumes in at-risk APOE4 women: results from the European Prevention of Alzheimer’s Disease (EPAD) cohortAssociation between right and left hippocampal volumes with age of HRT initiation. Multiple linear regression model showing the association between left and right hippocampal volumes and age of HRT initiation in non-APOE4 carriers (blue) and APOE4 carriers (red). Model-1 covariates: Age + years of education + handedness + marital status + CDR. Model-2: Model 1 covariates + age of HRT initiation (as an independent variable). Reported results are of model-2. APOE4 n= 27. non-APOE4 n= 46Back to article page
