Proportional hazards analysis of variables affecting survival
| Variable | β | SE | p Value | RR (95% CI) |
|---|---|---|---|---|
| β represents regression coefficients; SE is the standard error of β. | ||||
| Variables considered in the model were age, sex, NYHA class IV, third heart sound, cardiomegaly, alveolar oedema, systolic function (deteriorated or preserved), hypertension, hyperlipidaemia, diabetes, smoking, and ischaemic cardiopathy. Systolic function was forced into the final analysis. | ||||
| Age (years) | 0.050 | 0.011 | 0.000 | 1.05 (1.03 to 1.07) |
| Male sex | 0.584 | 0.226 | 0.010 | 1.79 (1.15 to 2.79) |
| NYHA IV | 0.498 | 0.247 | 0.044 | 1.65 (1.01 to 2.67) |
| Alveolar oedema | 0.518 | 0.240 | 0.031 | 1.68 (1.05 to 2.68) |
| Systolic function | 0.102 | 0.243 | 0.673 | 1.11 (0.69 to 1.78) |
