  1. β Regression coefficient; CI Confidence interval. β coefficients, 95% CIs, and p-values result from linear regression models that were adjusted for age and sex. β values are interpreted as the difference in means of the given AD-related molecule on the square root (tTau-TBS), cube root (apoE-TBSX, tTau-TBSX, tTau-FA), or natural logarithm scale (Aβ40-TBS, Aβ40-TBSX, Aβ40-FA, Aβ42-TBS, Aβ42-TBSX, Aβ42-FA, apoE-TBS, apoE-FA, pTau181-TBS, pTau181-TBSX, pTau181-FA) in comparison to the APOE3 group. P-values < 0.01 were considered as statistically significant after applying a Bonferroni correction for multiple testing separately for each fraction and each pair-wise comparison between APOE groups; significant findings are shown in bold
