Event Rates and Relative Risks for All‐Cause Mortality in 3266 Patients With Moderately Reduced Kidney Function (eGFR 30–60 mL/min per 1.73 m2) Who Underwent AVR With a Bioprosthesis or a Mechanical Valve
| Mechanical Valve | Bioprosthesis | |||||
|---|---|---|---|---|---|---|
| Events/PY | Crude Rate (95% CI) per 1000 PY | HR (95% CI) | Events/PY | Crude Rate (95% CI) per 1000 PY | HR (95% CI) | |
| Propensity‐score–matched cohort (n=960) | 230/3526 | 6.5 (5.7–7.4) | 1.00 | 220/3809 | 5.8 (5.1–6.6) | 0.85 (0.70–1.03) |

AVR indicates aortic valve replacement; eGFR, estimated glomerular filtration rate; HR, hazard ratio; PY, person‐years.
