MAPT and amyloidosis: In addition, the 95%CIs of the bootstrapped partial R2 distributions did not overlap for MMSE (amyloid-PET: CI = 0.026–0.028, mean = 0.027; tau-PET: CI = 0.126–0.133, mean = 0.130), ADAS13 (amyloid-PET: CI = 0.041–0.043, mean = 0.042; tau-PET: CI = 0.100–0.105, mean = 0.103), or ADNI-MEM (amyloid-PET: CI = 0.029–0.031, mean = 0.030; tau-PET: CI = 0.075–0.078, mean = 0.077), providing non-parametric support of a significant difference between amyloid-PET and tau-PET-derived partial R2 distributions.
