Abbreviations: CI, Confidence interval; ICH, Intracerebral hemorrhage; IVH, Intraventricular hemorrhage; mL, milliliters; OR: Odds ratio; VTE, venous thromboembolism.
aOnly cases where chemoprophylaxis was initiated prior to VTE diagnosis were considered. Bold font represents statistical significance.
