Data are shown as medians [interquartile ranges]. Probability was calculated with the Kruskal–Wallis test by ranks. If this test showed a significant result, a pairwise comparison was made with the Mann–Whitney U test. Significant calculated probability was set at 0.017 after the Bonferroni correction.
