Impact of HEM epitope mismatching on 1-hour PCI

Outcome	ITT HEM	PP HEM
N of evaluable transfusions	107	105
Adequate 1-hour increment
N of transfusions (% of total n of evaluable transfusions)	90 (84%)	88 (84%)
Mean (SD) n of epitope mismatches	3.2 (3.6)*	3.2 (3.6)
Inadequate 1-hour increment
N of transfusions (% of total n of evaluable transfusions)	17 (16%)	17 (16%)
Mean (SD) n of epitope mismatches	5.5 (5.3)*	5.5 (5.3)
OR of adequate increment per epitope mismatch (95% CI)†	0.85 (95% CI, 0.73-1.00)*	0.85 (95% CI, 0.73-1.00)
P†	.0485*	.0485

OR, odds ratio.

Excludes 2 transfusions where number of mismatches was not reported.

Adjusted for pretransfusion platelet count, period effect, and random participant effect.
