Comparisons in favorable outcomes rate according to use of intravenous thrombolysis prior to endovascular treatment after (A) and before propensity score-matching (B) according to key subgroups. 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; het, heterogeneity; NIHSS, National Institutes of Health Stroke Scale; ASPECTS, Alberta Stroke Program Early CT Score; MCA, middle cerebral artery. *Propensity score was calculated with all parameters in Table 1.
