Expected Percentage of Patients in Three Health States
| Time Post-stroke | Functional Independence, % (mRS 0–2) | Disability, % (mRS 3–5) | Death, % (mRS 6) |
|---|---|---|---|
| 3 monthsa | 30.3 | 47.5 | 22.2 |
| 6 months | 31.7 | 42.0 | 26.3 |
| 1 year | 29.9 | 36.5 | 33.6 |
| 2 years | 23.6 | 38.4 | 38.0 |
| 5 years | 15.4 | 28.6 | 56.0 |
Abbreviation: mRS, modified Rankin Scale.

We started with month 4 in calibration, so the targets were observations in month 6 or later. A total of 68% and 57% of survivors were in the disability state at the end of months 1 and 6, respectively, but the authors did not report the percentage who were disabled at 3 months.42 We assumed that the proportion of patients in disability at month 3 should be between the values in months 1 and 6, but closer to that of month 6, so we estimated that 61 % of survivors were disabled at 3 months.
