Figure 2. Distribution of 90-Day Modified Rankin Scale Score (mRS) in Patients Presenting in the Window 6 to 24 Hours After Time Last Seen Well With Internal Carotid Artery and Middle Cerebral Artery M1/M2 Occlusions, by Imaging Modality.

Figure 2.

Scores range from 0 to 6, with 0 indicating no symptoms; 1, no clinically significant disability; 2, slight disability (the patient is able to look after their own affairs without assistance but unable to carry out all previous activities); 3, moderate disability (patient requires some help but is able to walk unassisted); 4, moderately severe disability (patient is unable to attend to bodily needs without assistance and unable to walk unassisted); 5, severe disability (patient requires constant nursing care and attention); and 6, death. After adjustment of confounders, there was no difference in 90-day ordinal mRS shift between patients selected by computed tomography (CT) vs CT perfusion (CTP) (adjusted odds ratio, 0.95 [95% CI, 0.77-1.17]; P = .64) or CT vs magnetic resonance imaging (adjusted odds ratio, 0.95 [95% CI, 0.8-1.13]; P = .55).
