Number and percentage of patients achieving a clinically meaningful recanalization stratified against the CMR score
| CMR Score | Frequency of CMR (%) |
|---|---|
| 0 | 9/13 (69%) |
| 1 | 12/34 (35%) |
| 2 | 11/35 (31%) |
| 3 | 4/31 (13%) |
| 4 | 0/13 (0%) |
Note:—CMR score is the sum of the stratified NIHSS score and the occlusion location score. For NIHSS, 0 = NIHSS 0–7; 1 = NIHSS 8–14; 2 = NIHSS 15–20; 3 = NIHSS >20. For occlusions, ICA and proximal M1 = 1; distal M1 and M2–M4 segments = 0. Scores range from 0–4. A higher CMR corresponded to a lower frequency of successful recanalization with IV-rtPA.
