Demographic information for the subjects from the UK Biobank dataset, the Alzheimer’s Disease Neuroimaging Initiative (ADNI) dataset, and the Australian Imaging Biomarkers and Lifestyle Study of Ageing (AIBL) 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; EMCI = early mild cognitive impairment; LMCI = late mild cognitive impairment; AD = Alzheimer’s disease; MCI = mild cognitive impairment; SD = standard deviation.
