In this section, we present the performance results of each classification (AD vs. HC, MCIs vs. MCIc, AD vs. MCI, AD vs. MCIc, HC vs. MCIs, and HC vs. MCIc) for all five neuroimaging and APOE genotype modalities using whole-brain parcelation, the voxel-wise method, and the graphical method. Here, APOE is linked to Alzheimer disease.
