Table 4.

Logistic regression models fit to first pass effect, showing odds ratios for a one hour change in duration of stroke symptoms.

	Odds ratio	95% CI	p value
Model 1^*	0.93	0.88–0.98	0.012
Model 2^†	0.89	0.83–0.95	<0.001
Model 3^‡	0.93	0.88–0.99	0.017

Model 1 unadjusted.

^†

Model 2 adjusted for patient age, sex, race, baseline systolic blood pressure, NIH stroke scale, device (Solitaire vs. Trevo), site of occlusion, balloon guide catheter, clot aspiration, rescue treatment, intravenous alteplase, and intraarterial alteplase.

^‡

Model 3 adjusted for patient age, sex, atrial fibrillation, device (Solitaire vs. Trevo), balloon guide catheter, and rescue treatment.
