Data are mean ± SD (patients analysed) for CSR and plasma biomarkers as well as MRI results and median [minimum, maximum] (patients analysed) for cognitive and functional scales.

Differences between treatment groups were assessed by using t-test (two-sided, α=0.05) for CSF and plasma biomarkers as well as MRI results (displayed as difference between groups [95% confidence interval], p-value) and by calculating Hodges-Lehmann estimates and the corresponding non-parametric 95% confidence interval as well as by using Wilcoxon Rank Sum test (normal approximation, two-sided, α=0.05) for the cognitive and functional scales (displayed as Hodges-Lehmann estimate [95% confidence interval] p-value).
