Shift analysis and dichotomized scores on the modified Rankin scale
REGRESSION, TRANSFORMATION
The median mRS score was 2 (1–6) in the EVT alone group and 3 (1–6) in the bridging therapy group at follow-up 18 months. Ordinal regression analysis indicated that EVT alone couldn’t increase the functional improvement (adjusted common odds ratio [cOR] 0.96 [95 CI 0.60–1.54]). The number of patients with an excellent outcome (i.e., mRS score 0–1) in the EVT alone group were similar to patients in the bridging therapy group (38.8% vs. 39.0%; adjusted OR, 0.96 [95% CI, 0.53–1.74]) (Table Transformation of outcomes during the follow-up time
