aResults are presented as median (min–max), except where noted otherwise. WBC: white blood cell; Lym: lymphocytes; RBC: red blood cells; Hgb: hemoglobin; Hct: hematocrit; MCV: mean corpuscular volume; MCH: mean corpuscular hemoglobin; RDW: red cell distribution width; and Plat: platelets. Significance values are presented as p; ∗p < 0.05, ∗∗p < 0.005, ∗∗∗p < 0.0005, and ∗∗∗∗p < 0.00005.
