Table 4. Multivariate logistic regression analyses for association between each component of the ProVent model and ICU and hospital mortality.
| Variable | ICU mortality | Hospital mortality | ||||

| Adjusted OR (95% CI) | β value | p-value | Adjusted OR (95% CI) | β value | p-value | |
| Age ≥65 yr | 1.347 (0.695–2.609) | 0.298 | 0.378 | 1.569 (0.822–2.995) | 0.451 | 0.172 |

| Vasopressors | 4.505 (2.476–8.195) | 1.505 | <0.001 | 3.882 (2.157–6.988) | 1.356 | <0.001 |
| Hemodialysis | 5.429 (2.204–14.562) | 1.692 | 0.001 | 5.036 (1.894–13.393) | 1.617 | 0.001 |

The Hosmer-Lemeshow goodness-of-fitness statics were 4.578 (df=5, p=0.470) for ICU mortality and 6.928 (df=6, p=0.328) for hospital mortality, respectively.
ICU: intensive care unit; OR: odds ratio, CI: confidence interval.
