Groups 2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code | Source |
|---|---|---|---|---|---|---|
| Group 1 | Asundexian | Participants received asundexian 50 mg once a day (OD) and apixaban matching placebo. | 1 | 7,373 | OG000 | ClinicalTrials.gov |
| Group 2 | Apixaban | Participants received apixaban 5 mg twice a day (BID) or reduced dose 2.5 mg BID and asundexian matching placebo. | 6 | 7,364 | OG001 | ClinicalTrials.gov |

| Title | Number of Participants With Hemorrhagic Stroke | ClinicalTrials.gov |
| Description | The assessment was based on the cause-specific hazard ratio (csHR), comparing asundexian with apixaban which is based on time to first event.~Hemorrhagic stroke was defined as an acute, atraumatic extravasation of blood into the brain parenchyma, intraventricular or subarachnoid space with associated neurological symptoms. This does not include microbleeds or hemorrhagic transformation of an ischemic stroke. | ClinicalTrials.gov |
| Time frame | Approximately 12 months | ClinicalTrials.gov |
