Sample Size Calculation and Statistical Analysis
G*Power software (version 3.1.9; Heinrich Heine University) was used to estimate the required sample size. We estimated that the effect size of the changes in the primary outcome ABC total was 0.30 based on α=.05 and β=.80 in repeated-measures ANOVA. Thus, 34 children were required for each group. Considering a sample loss rate of 10%, an additional 4 participants were required for each group. Therefore, the total sample for this study was 76, with 38 participants in each group.Shapiro-Wilk test was used to test the normality of the data. The normally distributed variables were expressed as mean (SD) and categorical variables as frequency (%). Two-sided Student
