Data are expressed as numbers of individuals or means ± SD and comparisons were made by using the Chi-square test or Student’s-sample t-test, respectively. The bold p-values represent the significant differences between study groups. MCV: mean corpuscular volume, MCH: mean corpuscular hemoglobin, MCHC: mean corpuscular hemoglobin concentration.
