FIGURE 1.

Box and whisker plots of the change in bleeding assessment score, platelet count and hematocrit (Hct) pre‐transfusion to 1 hour post‐transfusion (0‐1) and to 24 hours post‐transfusion (0‐24) for the 2 groups (LP and CPP). The middle lines represent the median change, the boxes represent the 25% and 75% percentiles of the change and the whiskers represent the minimum and maximum changes in the variables. The horizontal dotted lines represent no change in the variable. Interpretations of the changes in variables above and below these zero change lines are provided. A, The change in (delta) bleeding score was significantly greater in the LP group compared to the CPP group at 1 hour post‐transfusion (ie, the bleeding score reduced more in the LP group than in the CPP group). There was no significant difference in this metric at the 24‐hour time point, however. B, There were no significant differences in the delta platelet count variable between the 2 groups at either the 1‐hour or the 24‐hour time points. In addition, the median delta variables were close to zero in both groups suggesting that on average neither of the products had any effect on the platelet count. There was no significant difference in this metric at the 24‐hour time point. C, The delta hematocrit was significantly greater in the CPP group compared to the LP group at 1‐hour post‐transfusion (ie, hematocrit decreased more in the CPP group), but there was no significant difference in the delta at the 24‐hour time point. CPP, cryopreserved platelets; LP, lyophilized platelets
