Alzheimer's disease (AD) is a neurodegenerative disease characterized by abnormal accumulation of amyloid beta (aβ) and hyperphosphorylation of tau protein
Fortunately, long-term presymptomatic stages of AD make it possible to intervene early with disease-modifying therapies
Currently, Aβ pathology can be identified by biomarker levels of amyloid-β positron emission tomography (Aβ-PET)
Patients assessed using Aβ-PET scans and plasma Aβ were included in this meta-analysis by searching online databases, including Embase, PubMed, and the Cochrane library

Meta-analysis results of Aβ40 group
Meta-analysis results of Aβ40 groupIn this meta-analysis, it was found that plasma Aβ40 values may not differ between PET (+) and PET (−)
In this meta-analysis, it was found that plasma Aβ40 values may not differ between PET (+) and PET (−)
Egger'stest results in Aβ40 group
Egger'sThis meta-analysis provides evidence that plasma Aβ40 values may not discriminate between PET(+) and PET(−) people.
