Note: The values in the table are presented as the median (interquartile range, Q3–Q1). χ2/Z and p represent the statistic and significance, respectively, of the Kruskal–Wallis test/Mann–Whitney U test. Different lowercase letters and * after data in the same row indicate significant differences at the 0.05 level in Kruskal–Wallis post hoc comparisons and the Mann–Whitney U test, respectively.
