Categorized subject groups. a Classification of subjects (n = 353) for the study. b Representative PiB-PET images of the study cohort (n = 353). Participants were classified as PiB-positive (PiB+) if the PiB retention (SUVR) value was >1.4 in at least one of the four ROIs (i.e., frontal, lateral temporal, lateral parietal, and PC-PRC) or PiB-negative (PiB–) if the SUVR values of all four ROIs were ≤1.4. – or + PiB-PET positivity, CN cognitively normal, MCI mild cognitive impairment, ADD Alzheimer’s disease dementia, ND nondemented, PiB-PET Pittsburgh-compound B positron emission tomography, SUVR standard uptake value ratio (Color figure online)
