Table 3. Factors associated with increased 3-year mortality (n = 1742).
| Covariate | Hazard Ratio | 95%CI | p-value | Non-proportionality p-value |
|---|---|---|---|---|
| Age | 1.58 | 1.47–1.71 | <0.0001 | NA |
| Male | 1.30 | 1.07–1.57 | 0.0074 | NA |
| CCI | 1.08 | 1.04–1.12 | <0.001 | NA |
| Day1 PSI (no age) | 1.01 | 1.01–1.02 | <0.0001 | NA |

| No AKI | 1 (reference) | |||
| Recovery vs. No AKI | 1.01 | 0.69–1.47 | 0.96 | NA |

Multivariable Gray’s model was used–Increased hazard ratios imply worse survival.
CCI: Charlson comorbidity index; AKI: Acute kidney injury
PSI: Pneumonia Severity Index
Age: 10 years unit
* For each variable, min and max hazard ratio among 10 time intervals are shown
