Figure 2
Platelet increments in response to individual platelet transfusions. The platelet increments (×109/L; ie, platelet counts after transfusion minus the pretransfusion count) are given for each transfusion. In the absence of further transfusions, increments that are rising are presumed to have a contribution from fetal platelet regeneration and are not included in the calculations of mean increments; these cells are shaded gray.
