Stepwise multivariate regression analysis for severity of hypoperfusion (dichotomized at median)
| Odds Ratio | 95% CI | P Value | Univariate r2 | |
|---|---|---|---|---|
| First step (multivariate r2 = 0.68) | ||||
| Age | 1.2 | 1.0–1.3 | .01 | 0.12 |
| TOAST | 0.76 | 0.15–4.2 | .77 | 0.004 |
| Baseline lesion volume | 1.1 | 1.0–1.2 | .04 | 0.12 |
| Baseline perfusion deficit | 1.0 | 0.99–1.0 | .06 | 0.12 |
| Sections with FHV (>4) | 6.7 | 1.0–41.9 | .04 | 0.26 |
| Smoking | 0.04 | 0.001–0.99 | .05 | 0.14 |
