FIGURE 3.

Distribution of functional scores at 90 days: A score of 0 on the modified Rankin scale indicates no symptoms; a score of 1, no clinically significant disability; and a score of 2, slight disability (patients are able to look after their affairs without assistance but are unable to carry out all previous activities); a score of 3, moderate disability (patients require some help but can walk unassisted); a score of 4, moderately severe disability (patients are unable to attend to bodily needs without assistance and are unable to walk unassisted); a score of 5, severe disability (patients require constant nursing care and attention); and a score of 6, death. We found that the proportion of functionally independent patients (mRS 0-3) at 90 days was higher in the preferred angioplasty group than in the preferred stent thrombectomy group (OR=3.681, 95% CI:1.009-13.428, P=0.048).
