Logistic Regression Models Showing Pre-Transfer Variables Independently Associated With Inter-hospital Arterial Recanalization

Model with occlusion site
	Unadjusted OR (95%CI)	Adjusted OR (95% CI)a	P value
Intravenous thrombolysis use	6.5 (3.9–11.0)	6.8 (4.0–11.6)	<0.001
Occlusion site			<0.001
ICA	Reference	Reference
M1 proximal	2.2 (1.0–4.9)	2.0 (0.9–4.5)
M1 distal	5.4 (2.5–11.7)	5.1 (2.3–11.5)
M2	4.3 (1.9–9.8)	5.0 (2.1–11.8)
Model with clot burden score
	Unadjusted OR (95%CI)	Adjusted OR (95% CI)a	P value
Intravenous thrombolysis use	6.5 (3.9–11.0)	6.6 (3.8–11.3)	<0.001
Clot burden score			<0.001
0–4	Referenc	Reference
5–7	3.3 (1.5–7.3)	3.4 (1.5–7.6)
8–9	5.1 (2.3–11.4)	5.6 (2.4–12.7)

^a:Variables not retained in the model: hypertension, diabetes, pre-stroke anticoagulants, glucose level, last-seen-well to imaging time.
