The accuracy of baseline tau PET uptake in predicting clinical conversion in the CU group was not evaluated separately, given that the number of CU individuals who converted to MCI or dementia (n = 9, 6% in Aβ(-) and n = 10, 14% in Aβ(+) individuals, Table 1) was not large enough to draw reliable conclusions. This evidence concerns the gene MAPT and dementia.
