marginally significantp = 0.053
In repeated 3 × 3 ANOVA, the sham vs standard tDCS contrast was significant, but only slightly below 0.05 threshold ( F (1, 17) = 4.544, p = 0.048, η p 2 = 0.211), while sham vs otDCS contrast was of similar effect size but marginally significant ( F (1, 17) = 4.319, p = 0.053, η p 2 = 0.203).
