A. Longer transfer time was associated with decreased likelihood of undergoing endovascular thrombectomy (ET). Odds ratio (OR) are from a binary logistic regression model and parameter estimates (β) are from linear regression models. Sample size (N), ASPECTS (Alberta Stroke Program Early CT Score), mRS (modified Rankin Scale).
B. Nocturnal transfer was associated with significantly longer delay. βs are from a multivariable regression model with time of transfer, day of transfer, and tPA administration as predictors, and with delay in transfer as the outcome. The overall model fit was significant (N = 234, R2 = 0.078, P <0.0005).
| A. Associations with transfer time | OR/β | N | P |
|---|---|---|---|
| Odds of undergoing ET | 0.990 | 234 | 0.004 |
| ASPECTS decrease during transfer | 0.000 | 200 | 0.961 |
| 90-day mRS for ET patients | 0.005 | 53 | 0.480 |
| B. Predictors of delay | β | Partial eta | P |
