Fig. 6: Associations between composite ROI measures of tau-associated FA, MD and tNDI with the CDR-SOB in the DLBs group. Amyloid-β status is denoted by color-coded lines with 95% confidence bands (blue = amyloid-β negative, red = amyloid-β positive).
From: Influences of amyloid-β and tau on white matter neurite alterations in dementia with Lewy bodies

Tau-associated white matter injury was statistically significant with CDR-SOB exclusively in the subgroup of DLBs who are amyloid-β positive.
