Why it matters

This is the first adequately powered RCT to compare anticoagulation strategies in ECMO, addressing a critical evidence gap. It suggests that less aggressive anticoagulation may reduce bleeding without increasing thrombotic risk, potentially improving outcomes in a high-stakes ICU population.
