Table 2

Factors associated with high volume of asymmetrical prominent veins.

Variable	Univariate analysis		Model 1		Model 2
	Crude OR (95% CI)	value	Adjusted OR (95% CI)	value	Adjusted OR (95% CI)	value
Atrial fibrillation	16.89 (4.37-65.32)	0.000	10.48 (1.78-61.68)	0.009
Baseline NIHSS score	1.14 (1.05-1.23)	0.001	1.03 (0.92-1.16)	1.033
Time to imaging (h)	0.81 (0.70-0.94)	0.005	0.84 (0.71-0.99)	0.038	0.79 (0.53-1.18)	0.247
DWI volume (mL)	1.10 (1.04-1.17)	0.002			1.06 (0.96-1.18)	0.271
Stenosis (50%)	660.0 (57.28-7604.88)	0.000			432.14 (30.93-6038.35)	0.000

Model 1: based on clinical inquiry and physical examination. Adjusted for history of atrial fibrillation, baseline NIHSS, and time to imaging (h). Model 2: based on relevant MR imaging data. Adjusted for time to imaging (h), DWI volume, and stenosis (50%).
