Variables associated with early recanalization in multivariable logistic regression.a
| β coefficient | Standard error | P | |
|---|---|---|---|
| HIR, per 10% increase | −1.19 | 0.43 | 0.006 |
| Thrombus length, per 1 mm increase | −0.78 | 0.22 | <0.001 |
| Occlusion site | 0.006 | ||
| ICA-T/L or M1 proximal | 0 (Reference) | – | |
| M1 distal or M2 | 1.54 | 0.56 | |
| Interaction term (HIR*thrombus length) | 0.09 | 0.04 | 0.02 |
Note: Due to the presence of an interaction term in the logistic model, results are presented as beta coefficients and standard error rather than odds ratios and 95% confidence intervals.
a
Twenty patients without visible susceptibility vessel sign were excluded from the model, which therefore included 198 patients (30 with early recanalization and 168 without).
HIR: hypoperfusion intensity ratio; ICA-T/L: intracranial internal carotid artery occlusion; M1: first segment of the middle cerebral artery; M2: second segment of the cerebral artery.
