Fig. 5From: Longitudinal resting-state EEG in amyloid-positive patients along the Alzheimer’s disease continuum: considerations for clinical trialsA-D Statistical power as a function of sample size (Aβ + MCI or AD dementia patients). The minimum required sample size per arm was estimated at 0.05 to 99% power for 1-year (A, C) and 2-year (B, D) trial duration. Effect sizes for EEG outcome measures were computed based on significant group-wise LMM results (Table S8, Additional file 2)Back to article page
