Authors' conclusion

This hypothesis-generating win ratio analysis, integrating death, thrombotic events, and major bleeds with and without quality of life, did not find an advantage of anticoagulation with edoxaban over no anticoagulation in patients with DDAF. The most common events were death and major bleeding.
