Incidence of Severe Uterine Bleeding Outcomes among Oral Anticoagulant Users and Nonusers

The risk of severe uterine bleeding (SUB) reported in oral anticoagulant (OA) clinical trials is likely underestimated due to the low representation of women of reproductive age. In a previous research letter, we reported SUB incidence in women who received OA treatment using real-world data. In this study, we examined the incidence of SUB among women presenting uterine bleeding (UB), with and without ongoing OA (warfarin or non-vitamin K oral anticoagulants) exposure, to contextualize our previous findings.
