  1. Different superscript letters indicate statistically significant differences in the same line according to Kruskal-Wallis and Mann-Whitney U tests (p < 0.05). Additionally, the group marked with * statistically different from other groups in same column according to Friedman and Wilcoxon tests (p < 0.05)
