Sample size calculation
The sample size calculation was based on the time-by-group interaction of a two-by-two mixed analysis of variance (ANOVA). The effect size was estimated to be 0.25 with 80% power and an α-value of 0.05. G*Power v.3.1.9.2 was used for this calculation. The estimated required sample size was 17 individuals per group. Considering the potential for loss, we aimed to recruit 20 participants per group.
