Platelet recovery model adjusted for age of transfused platelets.
Neurologic outcome model adjusted for ICH score.
ACI scores were missing for 2.4% (n = 3); percentages are from 122 patients, 76 with compatible transfusions and 46 with incompatible transfusions.
Three-month loss to follow-up was 28.8% (n = 36); percentages are from 89 patients, 49 with compatible transfusions and 40 with incompatible transfusions.
