Normally distributed data are expressed as mean ± SD; non-normally distributed data are expressed as median and interquartile spacing [M (Q1, Q3)]. WBC: White blood cells; LYM: Lymphocyte; RBC: Red blood cells; HGB: Hemoglobin; RDW: Red blood cell distribution width; PLT: Platelet; CEA: Carcinoembryonic antigen; HRR: Hemoglobin-to-red blood cell distribution width ratio; LRR: Lymphocyte-to-red blood cell distribution width ratio; PLR: Platelet-to-lymphocyte ratio.
