Comparison of how many external aortic root support (EARS) patients and how many patients in the comparison group had a red cell, platelet or fresh frozen plasma (FFP) transfusion
| Transfusion product | Number of patients | |
| EARS group (N=20) | Comparison group (N=18)* | |
| 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).
