| % patients who died as an inpatient | Median mRS at discharge | Median length of stay | |

| Pre-centralisation trend (units/time) | –0.2%/month (95% CI: –0.3 to 0.0)b | 0.00 mRS/month (95% CI: –0.0 to 0.0) | –0.1 days/month (95% CI: –0.2 to 0.1) |
| Step change immediately after centralisation (units) | 0.5% (95% CI: –3.3 to 4.3) | –0.1 mRS (95% CI: –0.3 to 0.15) | –4.9 days (95% CI: –8.1 to –1.7) |

aDependency as measured by the modified Rankin Scale15 (mRS): 0 – no symptoms; 1 – no significant disability despite symptoms, able to carry out all usual duties and activities; 2 – slight disability, unable to carry out all previous activities, but able to look after own affairs without assistance; 3 – moderate disability, requiring some help, but able to walk without assistance; 4 – moderately severe disability, unable to walk without assistance and unable to attend own bodily needs without assistance; 5 – severe disability, bedridden, incontinent and requiring constant nursing care; 6 – dead.
