Effect of the platelet count of the concentrate and the preparation method on 1-hour posttransfusion platelet count increments
Platelet . | Observed mean dose × 10-11 . | Estimated 1-hour platelet increment × 109/L for observed mean dose* . | Hypothetical equal dose × 10-11 . | Estimated 1-hour platelet increment × 109/L for hypothetical equal dose* . |
|---|---|---|---|---|
| Control PCs | 4.52 | 29.2/19.9 | 4.52 | 29.2/19.9 |
| UVB-PCs | 4.39 | 24.5/23.7 | 4.52 | 25.0/24.3 |
| F-PCs | 3.70 | 24.6/15.3 | 4.52 | 28.9/19.6 |
| F-APs | 3.68 | 27.9/18.6 | 4.52 | 34.0/24.7 |
