ICH = intracerebral hemorrhage; GCS = Glasgow Coma Scale; CI = confidence interval; mRS = modified Rankin Scale; IVH = intraventricular hemorrhage; ICP = intracranial pressure; INR = international normalized ratio; PTT = partial thromboplastin time.

Values based on pooled parameter estimates from multiply imputed data using chained equations with m=50.
