Exploring Hematoma Expansion Shift With Recombinant Factor VIIa: A Pooled Analysis of 4 Randomized Controlled Trials

Stroke Journal

Stroke, Volume 54, Issue 12 , Page 2990-2998, December 1, 2023. BACKGROUND:Hematoma expansion shift (HES) analysis can be used to assess the biological effect of a hemostatic therapy for intracerebral hemorrhage. In this study, we applied HES analysis to individual patient data from 4 randomized controlled trials evaluating rFVIIa (recombinant factor VIIa) 80 μg/kg to placebo.METHODS:We generated polychotomous strata of HES using absolute growth thresholds (≤0/<6/≥6 mL) and quintiles of p
