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