Adjusted association of CSF Aβ42 with cognitive assessments (A, B) and hippocampal volume (average right and left) (C) in the amyloid PET-positive cohorts. SUVR: standardized uptake value ratio; ADNI memory score; ADNI-EF: ADNI executive function; CI: confidence interval. The results are adjusted for age, sex, education, APOE4, centiloids, p-tau levels, and t-tau levels including intracranial volume for hippocampal volume analysis.
