  • 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.
