  1. Data presented as mean ± standard deviation. Different superscript lowercase letters (a, b, c) within a row indicate statistically significant differences over time (T0, T6, T12) according to the Friedman test followed by post-hoc Wilcoxon signed-rank tests with Bonferroni correction (p < 0.05). Identical letters within a row indicate no significant difference.
