Hematologic recovery and transfusion utilization following CAR19. (A-D) Sunburst charts showing the overlapping prevalence of lymphopenia, neutropenia, thrombocytopenia, and anemia across 4 time periods post–axi-cel infusion. Concentric rings are organized in a hierarchical structure outward from the origin, with overlapping segments representing shared cytopenias within the same patient(s); the numbers shown in each outer ring segment represent patient(s) with that unique combination of cytopenias. The prevalence of individual cytopenias are shown in the accompanying keys. (E) Swimmer plot showing utilization of blood and platelet transfusions and time of last growth factor (G-CSF) administration for severe neutropenia. Patients are identified by study number on the left, and clinical response categorization is indicated by the bar color.
