OR of survival at 365 days after admission by timing of stroke unit admission (adjusted for case mix using SSV and type of stroke)
| Admission to stroke unit (time in days) | Survival at 365 days OR (95% CI) |
|---|---|
| 0–1 | 1 |
| 2 | 0.89 (0.80 to 0.99) |
| 3 | 0.88 (0.76 to 1.01) |
| ≥4 | 0.78 (0.71 to 0.86) |
