| Risk factor | HR (95% CI) |
|---|---|
| Recipient age at transplantation (per 1-yr increase) | 1.03 (1.01–1.05) |
| Recipient sex (female v. male) | 0.53 (0.30–0.95) |
| Recipient body mass indexs (per 1 kg/m2 increase) | 1.08 (1.04–1.12) |
| Recipient history of diabetes (yes v. no) | 2.32 (1.40–3.83) |
| Recipient history of cardiovascular disease (yes v. no) | 1.53 (0.91–2.59) |
| Time receiving dialysis (per 1-yr increase) | 1.04 (0.96–1.11) |
| Donor age (per 1-yr increase) | 1.03 (1.01–1.05) |
| Donor type | |
| Deceased ECD v. living | 2.78 (1.51–5.13) |
| Deceased non-ECD v. living | 1.35 (0.73–2.48) |
| Cold ischemic time (per 1-h increase) | 1.06 (1.02–1.09) |
| Duration of surgery (per 1-h increase) | 1.93 (1.53–2.44) |
| Median household income (per $5000 increase) | 0.99 (0.96–1.03) |
| Transplantation period | |
| 2010–2012 v. 2005–2009 | 2.33 (1.27–4.27) |
| 2013–2015 v. 2005–2009 | 1.44 (0.74–2.83) |
CI = confidence interval; ECD = expanded-criteria donor; HR = hazard ratio.
