t-ratio, p value 95% CI
Variables ANOVA Model, p value CN-Dementia CN-MCI MCI-Dementia
CSF Aβ 1–42 F(2,45) = 3.28, p = 0.047 −2.50, 0.04 [−1460.52 – 23.12] - -
CSF t-tau F(2,45) = 7.25, p = 0.002 3.81, 0.001 [77.87–350.55] - 2.97, 0.01 [32.16 – 316.99]
CSF p-tau F(2,45) = 7.44, p = 0.002 3.86, 0.001 [8.41 – 36.86] - 2.96, 0.01 [3.31 – 33.03]

Only measures with significant clinical group differences (p < 0.05) following post hoc Tukey’s HSD test shown. No additional covariates added to models.

Abbreviations: Aβ1–42 = amyloid beta 1–42 peptide; ANOVA = analysis of variance; CN = cognitively normal; CSF = cerebrospinal fluid; HSD = honestly significant difference; MCI = mild cognitive impairment; p-tau = phosphorylated tau; t-tau = total tau
