Medians with common letters are insignificant in the same raw (i.e. Medians with dissimilar letters are significant)

Z: Wilcoxon signed ranks test

H: H for Kruskal Wallis test

P: p-value for comparing the three studied groups

p0: p-value for comparing between baseline and after 1.5 month

*: Statistically significant at p ≤ 0.05
