Figure 2.

Plasma Aβ42/40 levels independently predict longitudinal amyloid-PET deposition in non-demented individuals. Predicted trajectories for global amyloid-PET accumulation (z-scores) in relation to baseline plasma Aβ42/40 in a subsample (n = 86) with available amyloid-PET data. The models were fit using continuous Aβ42/40 values but for illustration purposes the plots show the trajectories for individuals with high, medium and low individuals with high, medium and low plasma Aβ42/40 tertiles. Plasma Aβ42/40 did not show significant results in the voxel-wise analyses, after adjusting for multiple comparisons.
