Results are shown as means ± SEM (SE – experimental group with suboptimal level of vitamin D, SC – control group with suboptimal level of vitamin D, OE – experimental group with optimal lever of vitamin D, OC – control group with optimal level of vitamin D); p (between groups) Kruskal-Wallis test; p (inside groups) Friedman test for dependent means; p (Test I vs Test II) Wilcoxon test
