I-Q = Interquartile range difference between the upper and lower observed quartiles.
Holm’s adjusted p-value = Lowest alpha level at which the respective difference between median values using the Wilcoxon rank sum test would be significant based on the Holm’s-Bonferroni test.
NS = adjusted p >0.05
