Comparisons in clinical outcomes according to use of intravenous thrombolysis prior to endovascular treatment after (A) and before propensity score-matching (B). Odds ratios (ORs) were calculated after handling missing values for variables included in the propensity score using a multiple imputation procedure. MT, mechanical thrombectomy; IVT, intravenous thrombolysis; CI, confidence interval; ICH, intracerebral hemorrhage; sICH, symptomatic intracerebral hemorrhage. *Pre-specified primary outcome defined as a 90-day mRS score of 0 to 2, or equal to pre-stroke modified Rankin Scale (mRS) score; † Defined as a 90-day mRS of 0 to 1, or equal to pre-stroke Rankin Score; ^‡ Defined as modified Thrombolysis In Cerebral Infarction (mTICI) 2b/3; ^§ Defined as mTICI 3; ^∥Propensity score was calculated with all parameters in Table 1.
