Statistical analysis
Data from 90 participants (30 participants in each group) were analyzed using the SPSS statistical software version 26 (SPSS Inc., Chicago, IL, USA). Baseline values of IS, ST, and SLTH were tested using the Shapiro–Wilk normality test for normal distribution, which revealed no normal distribution for several baseline values. Therefore, non-parametric tests were used for further with-in and between-group analyses. Wilcoxon Signed Ranks Test was used for with-in-group analysis, and Kruskal Wallis Test with post-hoc and Mann–Whitney U tests were used for between-group analyses. p ≤ 0.05 was regarded as significant, and the confidence interval was set at 95%. Effect sizes were calculated using the formula r = z/√n for Wilcoxon Signed Ranks and Mann–Whitney U test. This effect size was interpreted as r less than 0.3—small effect, r between 0.3 and 0.5—medium effect, r greater than 0.5—large effect
