Markers of the amyloid cascade of study participants. P-values were calculated by using one-way ANOVA with Bonferroni’s correction for continuous Gaussian variables (or Kruskall-Wallis test with Dunn’s correction for non-Gaussian variables) for the amyloid load (A), plasma NfL (C) and cognitive measures (D–E) but not for pTau-181 (B), where Mann–Whitney test was applied. Data are presented as box-plots with black horizontal lines indicating medians and circles indicating the subject’s values. Abbreviations: CU, cognitively unimpaired persons; CI-NAD, patients with cognitive impairment not due to AD; CI-AD, patients with cognitive impairment due to AD
