Description

A study using Medicare data concluded that among patients aged 65 years or older, rivaroxaban had a less favorable benefit-harm profile compared with other non-vitamin K oral anticoagulants (NOACs); however, it is unclear whether this finding persists in younger users. To compare major extracranial bleeding (MEB), gastrointestinal bleeding (GIB), intracranial hemorrhage (ICH), and thromboembolic stroke in individuals aged younger than 65 years using non-vitamin K oral anticoagulants (NOAC users) for nonvalvular atrial fibrillation (NVAF).
