Mann-Whitney U test was performed to compare males and females. P<0.05 was considered statistically significant (p-values of significant variable in bold print). TWBC: Total White Blood Cells; RBC: Red Blood Cells; HCT: Haematocrit; MCV: Mean Cell Volume, MCH: Mean Cell Haemoglobin; MCHC: Mean Cell Haemoglobin Concentration; RDW-CV: Red cell Distribution Width-Coefficient of Variation; Abs: Absolute.
