Fig. 3.

Distributions of modified Rankin Scale at 90 days in the four subgroups stratified by NIHSS and infarct core volume. A generalised odds ratio (gOR) and 95% confidence interval (95%CI) in each subgroup is provided in the figure to present a shift in the distribution of mRS scores toward a better outcome between the endovascular therapy and medical-management arms. A gOR >1 favored the endovascular therapy arm over the medical-management arm. Abbreviations: mRS indicates modified Rankin Scale; NIHSS, National Institutes of Health Stroke Scale; EVT, endovascular therapy; MM, medical management; gOR, generalised odds ratio; CI, confidence interval.
