Three-month proximal composite performance by intervention group. Between-group differences on proximal composite as evidenced by Bonferonni-adjusted RM-ANCOVA. Covariates appearing in the model were evaluated at the following values: age = 71.11, sex = 0.45, years of education = 16.19, tDCS group = 0.50. Findings demonstrated that intervention groups did not differ at baseline, both groups improved significantly from baseline to 3-month assessments, and the cognitive training group (black) improved significantly more compared to the education training group (gray)
