Statistical analysis
The Kolmogorov–Smirnov test was employed to assay the normal distribution of variables. The one-way ANOVA and Kruskal-Wallis test were employed to compare Anthropometric and Biochemical factors between groups. Post Hoc and Mann-Whitney tests were utilized to compare subgroups (I, II, III). All statistical analyses were performed using SPSS version 17 (SPSS, Chicago, IL, USA).
