IQR Interquartile range, SD Standard deviation, H Kruskal–Wallis test, pairwise comparison bet. each 2 groups was done using post hoc test (Dunn’s for multiple comparisons test); p, p value for comparing between the different studied groups; p₀, p value for comparing between group 4 and each other group; p₁ p value for comparing between group 1 and deficient; p₂, p value for comparing between group 1 and normal; p₃, p value for comparing between deficient and normal
