Distribution of the modified Rankin Scale (mRS) scores at 90 days. No significant difference was seen between the tenecteplase and alteplase groups in the ordinal analysis of the mRS score, adjusted for age, sex, baseline stroke severity, symptom onset-to-needle as fixed-effects variables, and site as a random-effects variable (adjusted common odds ratio, 0.87 [0.62 to 1.20], P=0.39). The mRS score ranges from 0 to 6, with 0 indicating no symptoms, 1 no clinically significant disability, 2 slight disability, 3 moderate disability, 4 moderately severe disability, 5 severe disability, and 6 death.
