Logistic regression models fit to reperfusion, showing odds ratios for a one hour change in duration of stroke symptoms in stratified subgroups.

Variable	Odds ratio*	95% CI	p value
Patient sex
Male (n=250)	0.87	0.76–0.99	0.029
Female (n=256)	0.90	0.83–0.98	0.016
Occlusion site
Middle cerebral artery (n=369)	0.91	0.85–0.98	0.016
Internal carotid artery (n=137)	0.84	0.68–1.05	0.119
Guide catheter
Balloon guide (n=264)	0.95	0.86–1.06	0.362
Conventional/Distal access (n=242)	0.83	0.75–0.92	0.001

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