Assessment

Primary outcomes

The effect of DOAC trough drug blood level and FXa activity in post-EST bleeding in patients taking DOAC

Key secondary outcomes

(1) Influence of drug-metabolizing enzyme gene polymorphisms on gastrointestinal bleeding after EST in patients taking DOACs
(2) The influence of blood coagulation markers on gastrointestinal bleeding after EST in patients taking DOACs
(3) Extracting the characteristics of factors related to endoscopic treatment in gastrointestinal bleeding after EST in patients taking DOACs
(4) Differences in DOACs in gastrointestinal bleeding after EST in patients taking DOACs
(5) The relevance of CHADs scores in gastrointestinal bleeding after EST in patients taking DOACs
