Prediction of Death after one Year
| Risk factors | Odds ratio | 95 % Confidence interval | p |
|---|---|---|---|
| Sex | 1.24 | 0.48–3.22 | 0.65 |
| Age | 1.10 | 1.05–1.15 | < 0.0001 |
| WFNS Grade | 4.67 | 2.49–8.75 | < 0.0001 |
| Pneumonia | 0.64 | 0.20–2.07 | 0.46 |
| Sepsis | 6.08 | 1.16–32.04 | 0.033 |
| Hydrocephalus | 6.46 | 2.14–19.51 | 0.00095 |
| Shunt | 0.18 | 0.042–0.81 | 0.025 |
| Diabetes insipidus | 0.28 | 0.058–1.35 | 0.11 |
| Tracheostomy | 0.09 | 0.021–0.41 | 0.0016 |
| Decompressive craniectomy | 6.17 | 1.47–25.85 | 0.013 |
Binary logistic regression was performed as a multivariate analysis with dichotomized status of death (0 = “alive”; 1 = “dead”) as the dependent variable and sex, age, WFNS grade, pneumonia, sepsis, hydrocephalus, shunt, diabetes insipidus, tracheostomy and decompressive craniectomy as independent variables (covariates)
