Median (range), N (%).

The amount of apheresis platelets were calculated by converting to 6 units of platelet concentrate. One patient of each group received 8 units of apheresis platelets;

The transfusion episode considers several blood products transfused on the same day as 1 episode.

Abbreviations: RBC, red blood cell; FFP, fresh frozen plasma; PC, platelet concentrate; AP, apheresis platelet.
