*The multiple logistic regression test was used to analyze ORs. Outcomes at 90 days used adjusted variables: age, NIHSS baseline, diabetes mellitus.
†Common OR; the primary analysis involved 92 patients in the EVT group and 28 patients in the SMT group. Scores on the mRS of functional disability range from 0 (no symptoms) to 6 (death). The common OR was estimated from an ordinal logistic regression model and indicates the odds of improvement of 1 point on the mRS, with a common OR >1 favoring the endovascular treatment.
EVT, endovascular treatment; mRS, modified Rankin Scale; NIHSS, National Institutes of Health Stroke Scale; OR, odds ratio; sICH, symptomatic intracranial hemorrhage; SMT, standard medical treatment.
