To investigate the association between oral anticoagulants and the incidence of abnormal uterine bleeding.
Conducted a randomized trial with participants using oral anticoagulants.
Monitored the rate of abnormal uterine bleeding events among the participants.
Participants on oral anticoagulants experienced a significantly higher rate of abnormal uterine bleeding compared to those not on anticoagulants (exact rates not specified).
The odds ratio for increased bleeding associated with anticoagulants was notable, indicating elevated risk.
