Figure 2. Percent Distribution of Modified Rankin Scale (mRS) Scores at 90 Days by Treatment in the Modified Intention-to-Treat Population.

Shown are mRS scales for patients in the direct transfer to angiography suite (DTAS) group and the direct transfer to computed tomography (DTCT) group who were evaluated by a central assessor blinded to group assignment. There was a significant difference between the DTAS group and the control DTCT group in the overall distribution of scores after adjustment for age, National Institutes of Health Stroke Scale score at baseline, time from stroke onset to admission, premorbid functional status, and atrial fibrillation (adjusted common odds ratio for improvement of 1 point on mRS, 2.2; 95% CI, 1.2-4.1).
