r: Effect size * Mann-Whitney U test; P^a Friedman test; ^b Wilcoxon Signed-Ranks test; W0-3, W0-7, W3-7: Pre-post treatment differences; Median (1st quartile–3rd quartile) for non-normal distribution values were used. Adjusted p-values were considered significant based on Bonferroni correction
W0: Baseline assessment (pre-treatment)
W3: Assessment immediately after treatment completion (week three)
W7: Assessment 4 weeks after treatment completion (week seven)
