Multivariable survival analysis using Cox’s regression model.
| Variable | Hazard ratio | Confidence range (95%) | value |
| NT-proBNP levels (2 groups: above and below the third quartile border, 8548.5 pg/mL) | 0.33 | [0.13; 0.75] | 0.0132 | Age (2 groups: above and below the third quartile border, 82 years old) | 0.44 | [0.2; 0.9] | 0.0319 | EF (2 groups: above and below the third quartile border, 50%) | 4.06 | [2.26; 7.36] | 0.0001 |
