Graphs showing the variation of the mean count of each bone marrow lineage as a function of time. (a) Mean white blood cell count (×1000 cells/μL) over time. Leukocytosis was noted since admission with no significant drop in white blood cell count observed during hospitalization. (b) Variation of mean hemoglobin level (g/dL) over time with acute drop in hemoglobin level observed within 3 days of admission. (c) Variation of mean platelet count (×1000 platelets/μL) over time showing a significant decrease of platelet count within 3 days of admission.
