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.
