Normally distributed values are expressed as mean (95% CI) and nonnormally distributed values are expressed as median (IQR). RBC: red blood cells; MCH: mean cell hemoglobin; MCHC: mean corpuscular hemoglobin concentration; MCV: mean corpuscular volume; RDW-CV: red cell distribution width; PLT: platelets; WBC: white blood cell (leukocyte) count; Hb: hemoglobin; HCT: hematocrit; RET: reticulocyte count; RET%: percentage of reticulocytes. ^NSnonsignificant, , , and compared to baseline.
