Table 4:

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.
