Plasma and CSF GFAP concentrations are increased in amyloid-β-positive groups. Violin plots with median values for plasma and CSF GFAP (z-scores) in amyloid-β-negative cognitively unimpaired individuals (CU Aβ−), amyloid-β-positive cognitively unimpaired individuals (CU Aβ+), amyloid-β-positive cognitively impaired individuals (CI Aβ+), amyloid-β-negative cognitively impaired individuals (CI Aβ−) and non-Alzheimer’s disease disorders, after adjusting for age and sex. *Significant group differences after adjusting for multiple comparisons with FDR corrections (q < 0.05).
