Similar to section “Association Analysis Between Features on Regions of Interest and Measure for Amyloid-β and Tau Deposition,” we also chose 1,500 RD and 1,500 TBM from the four ROIs (Aβ, Braak12, and Braak34) and 3,000 features from 1,500 random-selected vertices on the whole hippocampal surface to predict the conversion rates from MCI to AD, respectively. Here, MAPT is linked to Alzheimer disease.
