SD: standard deviation Z: Wilcoxon signed ranks test t: paired t-test

Means in the same raw with common letters are not significant (i.e., Means with Different letters are significant)

F: F for ANOVA test, pairwise comparison between every 2 groups were done using Post Hoc Test (Tukey)

H: H for Kruskal Wallis test, pairwise comparison between every 2 groups were done using Post Hoc Test (Dunn’s for multiple comparisons test)

p₀: p-value for comparing between baseline and after 1.5 month p₁: p-value for comparing Group I and Group II

p₂: p-value for comparing Group I and Group III p₃: p-value for comparing Group II and Group III *: Statistically significant at p ≤ 0.05
