↵a Excellent outcome was defined as 90-day mRS ≤ 1, and favorable outcome, as 90-day mRS ≤ 2. ORs were calculated using mTICI 2b reperfusion as a reference.
↵b Adjusted on center, age, diabetes, admission NIHSS score, prior use of IV thrombolysis, site of occlusion, favorable collateral flow, etiology, and onset to reperfusion time using multivariable logistic regression models (after a mean of 10 imputations to handle missing data on favorable collateral flow).
