Independent predictors of 1-year mortality in men.
| HR | CI 95% | p-value | |
|---|---|---|---|
| Hemoglobin (g/dl) | 0.68 | 0.57–0.80 | <0.001 |
| Sodium (mEq/L) | 0.94 | 0.86–1.02 | 0.17 |
| NT-proBNP (pg/ml) | 1.00 | 1.00–1.00 | <0.001 |
| Frailty (FRAIL) | 1.45 | 0.81–2.59 | 0.20 |
| Hemoglobin (g/dl) | 0.67 | 0.56–0.79 | <0.001 |
| Sodium (mEq/L) | 0.95 | 0.87–1.03 | 0.24 |
| NT-proBNP (pg/ml) | 1.00 | 1.00–1.00 | <0.001 |
| Frailty (CFS) | 1.36 | 0.71–2.58 | 0.34 |
| Hemoglobin (g/dl) | 0.68 | 0.58–0.80 | <0.001 |
| Sodium (mEq/L) | 0.94 | 0.87–1.03 | 0.21 |
| NT-proBNP (pg/ml) | 1.00 | 1.00–1.00 | 0.001 |
| Frailty (mobility visual scale ≥2) | 1.95 | 1.04–3.67 | 0.03 |
A Cox regression was performed for each of the different frailty scales to avoid collinearity between them: in each case, the significant variables (p < 0.001) were included in the log-rank test and the corresponding frailty scale.
