From: Characterization of Alzheimer’s tau biomarker discordance using plasma, CSF, and PET
Cross-sectional characteristics of tau biomarker groups. a Plasma/CSF group. b Plasma/PET group. The frequency of APOE ε4 allele, Aβ pathology, and MCI, as well as the Aβ burden (reflected by CSF Aβ42 concentrations and Aβ-PET SUVRs), was compared. Significance levels for group comparisons: *P < 0.05, **P < 0.01, ***P < 0.001. Abbreviations: Aβ, amyloid-β; CN, cognitively normal; CSF, cerebrospinal fluid; MCI, mild cognitive impairment; PET, positron emission tomography; SUVR, standard uptake value ratio
