Longitudinal changes in cognitive scores and hippocampal volumes. a Plasma/CSF group. b Plasma/PET group. All outcome variables were standardized to z-scores to facilitate comparisons between modalities. Alterations in clinical outcomes over time were modeled using linear mixed-effects regression with data from different visits. Abbreviations: CSF, cerebrospinal fluid; PET, positron emission tomography
