Favorable for the primary efficacy outcome is defined as a modified Rankin scale (mRS) score of 0 in patients with mild stroke (baseline NIHSS score, 3-7), mRS score of 0 to 1 in patients with moderate stroke (baseline NIHSS score, 8-14), and mRS score of 0 to 2 in patients with severe stroke (baseline NIHSS score, 15-22).
The analysis for the primary outcome included missing data imputed by a multiple-imputation method.
The adjusted risk difference for the primary outcome was adjusted for baseline stroke severity (NIHSS scores of 3-7 [mild], 8-14 [moderate], and 15-22 [severe]) and thrombolysis use (yes or no).
