| Total hemorrhage 1 | Lower gastrointestinal hemorrhage 2 | Upper gastrointestinal hemorrhage 2 | Intra-cerebral hemorrhage 2 | Subarachnoid hemorrhage 2 | Gastrointestinal endoscopy 3 | |
|---|---|---|---|---|---|---|
| N = 11, 173 | 1612 | 992 | 677 | 95 | 11 | 1660 |
| 3-year cumulative incidence (%) | 14.43 | 8.88 | 6.06 | 0.85 | 0.10 | 14.86 |
| Event rate (per 1000 patient-years) | 52.64 | 31.21 | 20.94 | 2.85 | 0.33 | 54.45 |
1Counted as the first major hemorrhage at any anatomical location.
2Counted as the first hemorrhage at this anatomical location.
3Gastrointestinal endoscopy included gastroscopy, colonoscopy, sigmoidoscopy, duodenoscopy & esophagoscopy, when the procedure occurred during hospital stay.
