Patterns of Follow‐Up Change in mRS Between Days 1, 28, 90, 180, and 365
| Day 1 (n=1276) | Day 28 (n=1263) | Day 90 (n=1253) | Day 180 (n=1249) | Day 365 (n=1246) | |
|---|---|---|---|---|---|
| Worsening, n (%) | … | 24 (2) | 34 (3) | 44 (4) | 66 (5) |
| No change, n (%) | … | 536 (42) | 676 (54) | 853 (68) | 1002 (80) |
| Improving, n (%) | … | 703 (56) | 543 (43) | 352 (28) | 178 (15) |
| Incremental deaths, n (%) | 9 (1) | 12 (1) | 7 (1) | 18 (1) | |
| mRS, mean (SD) | 3.3 (0.0) | 2.6 (0.0) | 2.1 (0.0) | 1.8 (0.0) | 1.7 (0.0) |
| mRS, median (IQR) | 4 (1) | 3 (1) | 2 (2) | 1 (2) | 1 (2) |
| mRS change, mean (SD) | … | −0.8 (0.9) | −0.5 (0.8) | −0.3 (0.6) | −0.1 (0.6) |
Worsening, no change, and improving refer to the difference between the participant’s mRS score at one assessment compared with the previous. For example, at day 90, 34 (3%) individuals had a worse (higher) mRS score than at day 28. Incremental deaths refer to new deaths between follow‐ups. IQR indicates interquartile range; and mRS, modified Rankin Scale.
