Multivariable logistic regression analysis for additional primary outcome (excellent reperfusion (TICI 2c /3) after first pass retrieval)

Predictors	First-Pass reperfusion
	OR	95% CI	p-value
COVES	1.2	1.04 to 1.36	0.011
Time from onset to reperfusion	0.999	0.999 to 1.001	0.443
Penumbra volume Tmax >6 s	0.998	0.995 to 0.999	0.038
Observations n=518

Multivariable regression analysis in table 5 demonstrates calculated OR, 95% CI and p-value of all available (n=518) first pass- and non-first pass-reperfused patients with a TICI score of 2 c/3 within the first retrieval attempt after mechanical thrombectomy.

N=75 patients had unknown times from symptom onset to reperfusion and in 24 patients the exact penumbra volume was unknown.

COVES, cortical vein opacification score;TICI, Thrombolysis in Cerebral Infarction.
