| Previous TIA/ischemic stroke | 2.24 | 0.95–5.31 | 0.067 | 1.55 | 0.87–2.75 | 0.134 |
| Stroke severity (NIHSS) | 1.15 | 1.10–1.20 | <0.001 | 1.10 | 1.07–1.13 | <0.001 |
*HR for increase of age by one year or presence of a specific medical condition.
HR <1 indicates factor favours survival; HR >1 indicates factor is associated with poor survival.
