Voxel‐based associations of PiB SUVr with plasma biomarkers of GFAP, NfL, and p‐tau‐181 in the whole group of patients within the DLB continuum are displayed in Figure 2C, demonstrating that higher PiB SUVr was associated with higher levels of plasma GFAP, NfL, and p‐tau‐181 across the whole cortex in a homogenous manner. Here, GFAP is linked to Lewy body dementia.
