Final model selected by multivariate Cox proportional hazards modelling as simplest description of cardiovascular mortality of the cohort of patients
| Variable | Units/coding | Hazard ratio | 95% CI | χ2(LRT) | p Value |
| Age | 10 years | 1.26 | 1.01 to 1.57 | 4.31 | 0.04 |
| Crackles | 0=none | 2.13 | 1.50 to 3.02 | 20.5 | <0.001 |
| 1=basal | |||||
| 2=more than basal | |||||
| SBP | 10 mm Hg | 0.88 | 0.83 to 0.94 | 17. 7 | <0.001 |
| Creatinine | μmol (log)4-150 | 2.64 | 1.87 to 3.74 | 24.9 | <0.001 |
Creatinine values were log transformed before entry into the model.
↵4-150 Hazard ratio for a doubling in serum creatinine concentration.
CI, confidence interval; LRT, likelihood ratio test; SBP, systolic blood pressure.
