↵a Revised hematoma expansion was defined as any of a ≥ 6-mL or ≥33% increase in ICH volume, a ≥ 1-mL increase in intraventricular hemorrhage volume, or de novo intraventricular hemorrhage.
↵b Adjusted for antiplatelet use, anticoagulant use, baseline ICH volume, and last-seen-well to initial CT.
↵c P < .05.
