Table 2.
Death or major cardiovascular events among kidney donors and non-donors
| Donors (n=2028) | Non-donors (n=20 280) | |
|---|---|---|
| Median (IQR) follow-up (years) | 6.8 (3.7 to 10.9) | 6.4 (3.5 to 10.6) |
| Range follow-up (years) | 0.5-17.7 | 0.1-17.7 |
| Total follow-up (person years) | 15 176 | 147 332 |
| No (%) of events | 42 (2.1) | 610 (3.0) |
| No of events per 1000 person years* | 2.8 | 4.1 |
| Model based risk ratios (95% CI) | 0.66 (0.48 to 0.90) | 1.0 (reference) |
| No (%) of types of events†: | ||
| Death | 16 (0.8) | 365 (1.8) |
| Acute myocardial infarction | 14 (0.7) | 141 (0.7) |
| Coronary artery angioplasty or surgery | 15 (0.7) | 179 (0.9) |
| Stroke | 5 (0.2) | 51 (0.2) |
IQR=interquartile range.
*P=0.01, stratified log rank test.
†Events of carotid endarterectomy, abdominal aortic aneurysm repair, and peripheral vascular bypass surgery were rare (≤25 events for all three outcomes combined for donors and non-donors combined) and are not reported here for reasons of privacy. Events reported here are not mutually exclusive; individual might have had more than one event in follow-up. In survival models we considered time to first event.
