Flowchart, shows the initial number of participants and those excluded for any reason. A+ = amyloid β positive, A− = amyloid β negative, AD = Alzheimer disease, ADNI = AD Neuroimaging Initiative, AV-1451 = flortaucipir, CSF = cerebrospinal fluid, GRE = gradient echo, MH = microhemorrhage, TN+ = tau/neurodegeneration positive, TN− = tau/neurodegeneration negative.
