Note: Data are and median (IQR). values for differences between the two groups were obtained by the Student -test or the Mann–Whitney U test. IQR: interquartile range; WBC: white blood cells; LYM: lymphocytes; NEU: neutrophil; NLR: neutrophil-to-lymphocyte ratio; MO: monocyte; monocyte-to-lymphocyte ratio; EOS: eosinophil; RBC: red blood cells; HGB: hemoglobin; PLT: platelet cells; HCT: hematocrit; MCV: mean corpuscular volume; MCH: mean corpuscular hemoglobin; MCHC: mean corpuscular hemoglobin concentration; ESR: erythrocyte sedimentation rate; INR: international normalized ratio; PT: prothrombin time; PTT: partial thromboplastin time. The threshold for significance is the Bonferroni-corrected from to .
