Table 2.
Demographic information for the subjects from the Alzheimer’s Disease Repository Without Borders (ARWiBo) dataset, the Open Access Series of Imaging Studies: Cross-Sectional (OASIS-1) dataset, and the Minimal Interval Resonance Imaging in Alzheimer's Disease (MIRIAD) dataset. We used ANOVA test and the chi‐square test of homogeneity to test for significant differences in age and sex between healthy controls and patients. Abbreviations: HC = healthy control; AD = Alzheimer’s disease; MCI = mild cognitive impairment; SD = standard deviation.
