↵a ORs were calculated using a backward-stepwise multivariable penalized-likelihood logistic model. Candidate predictors in model 1 were mothership, admission to intensive care, atrial fibrillation, pretreatment NIHSS, pretreatment ASPECTS, pretreatment DWI BSS, IV thrombolysis, PcomA collateral flow, thalamus involvement, and onset-to-groin puncture time. Candidate predictors in model 2 were mothership, admission to intensive care, atrial fibrillation, pretreatment NIHSS, pretreatment PC-ASPECTS, pretreatment DWI BSS, IV thrombolysis, PcomA collateral flow, thalamus involvement, onset-to-groin puncture time, and complete recanalization (mTICI 3).
