Intergroup comparisons used Kruskal-Wallis H testfollowed by Dunn’s post-hoc test for significant results. Intragroup comparisons used Friedman and Wilcoxon tests. Categorical variables were analyzed using Pearson’s chi-squared test. Statistical significance was set at p < 0.05. Continuous variables are presented as mean ± standard deviation (SD).
