Linear regression models showing associations between CSF AD biomarker levels (Aβ42 level, ratio of t-tau/Aβ42) and plasma AD biomarkers in all ADNI subjects with CSF and plasma analytes (n = 566)^a

Abbreviations: Aβ42 = β-amyloid 1–42; AD = Alzheimer disease; ADNI = Alzheimer's Disease Neuroimaging Initiative; BNP = B-type natriuretic peptide; t-tau = total tau.

^aSimilar correlations were observed in ADNI subjects with CSF and plasma analytes not treated with cholinesterase inhibitors (n = 304; see appendix e-1).
