a
Hematological parameters and Age were statistically described by median (P25,P75), Kruskal-wallis nonparametric test was used to analyze the significance of hematological parameters in each group, with 95 % confidence interval (two-sided). Pearson's chi-square test was used to test the significance of sex composition ratio among all groups.
