Data presented as mean (SD).
a
Paired t-test between baseline and follow-up assessment.
b
Repeated-measures ANOVA testing interaction of intervention (EG vs. CG) per time (baseline vs. follow-up) for each outcome; adjusted for age and years of education. F test and p-value (*<0.05; **<0.01; ***<0.001); effect size is partial eta squared (ηpartial2) for group × time.
Significant values are in bold.
