As in NL, age was correlated with subject scores (or AD-designation by SVM) in stable MCI patients (p < 0.001; Pearson’s correlation for GLM and SSM/PCA and student t-test for SVM; Fig. 3B,C), while Aβ, tau or phosphorylated tau concentrations were not associated with subject scores (p > 0.2, Pearson’s correlation for GLM and SSM/PCA) and AD-designation (p > 0.11, student t-test). Here, MAPT is linked to Alzheimer disease.
