Odds ratios for unassisted AVF maturation versus assisted maturation and nonmaturation: multivariable analysis

Variable	Odds Ratio	95% CI	P Value
Blood flow, ml/min, per 100 ml/min	1.30	1.18 to 1.45	<0.001
AVF location, forearm versus upper arm	0.37	0.08 to 1.78	0.21
Stenosis	0.45	0.23 to 0.88	0.02
Depth, per 1 mm	0.88	0.77 to 1.00	0.05
Depth interaction with AVF location	0.50	0.28 to 0.84	0.02

Overall P value for the model <0.001. AVF, arteriovenous fistula; 95% CI, 95% confidence interval.
