* Statistically Significant at p = 0.05
** Values are presented as mean [± SD] and median (range). Statistical significance for between-group comparisons (same row) was determined using Kruskal-Wallis test followed by Dunn’s post hoc test for pairwise comparisons. Within-group comparisons (same column) were analyzed using Friedman test followed by Dunn’s post hoc test for pairwise comparisons
*** Different lowercase letters (a, b, c) indicate significant differences between groups at each time point
**** Different uppercase letters (A, B, C, D) denote significant differences within groups over time
