Association between plasma GFAP levels and Aβ-SUVR values stratified by APOE genotype. SUVR, standardized uptake value ratio; GFAP, glial fibrillary acidic protein. Co-variation of plasma GFAP and Aβ-PET retention extracted from the same location of the MRS volume. The participants were stratified in APOE ε4 carriers and non-carriers (Aβ-PET∼GFAP: P < 0.001 in APOE ε4 carriers, P < 0.001 in APOE ε4 non-carriers). The analysis was run in a subset of 288 participant with available plasma GFAP. The translucent area around the regression line represents the 95% confidential interval for the regression estimate.
