CSF pT217/T217 had the highest correlation with amyloid PET Centiloid of all the measures (Spearman’s ρ = 0.76 (95% CI 0.73–0.79), which was almost significantly higher than Lumipulse Aβ42/Aβ40 ( ρ = −0.74 (−0.77 to −0.71), P = 0.08) and was significantly higher than p-tau217 concentration (ρ = 0.71 (0.67–0.74), P < 0.0001) (Supplementary Tables 4 and 5 ).
