Fig. 4From: Longitudinal resting-state EEG in amyloid-positive patients along the Alzheimer’s disease continuum: considerations for clinical trialsA-B Statistical power as a function of sample size (Aβ + MCI and AD dementia). The minimum required sample size per arm was estimated at 0.05 to 99% power for 1-year (A) and 2-year (B) trial duration. Effect sizes for EEG outcome measures were computed based on significant whole-group LMM results (Table S7, Additional file 2)Back to article page
