Red cell 1 9
Platelet 0 9
FFP 0 12

Note that of the EARS group, 1/20 patients received a single unit red cell transfusion. Of the comparison group (*data missing for two patients), 9/18 were recorded as receiving red cell transfusions (mean 2.0 units per transfused patient), 9/18 received platelet transfusions (mean 1.6 units per transfused patient) and 12/18 received FFP transfusions (mean 4.8 units per transfused patient).
