Table 2.

Number of interventions after cannulation by number of interventions to promote AVF maturation

	Zero Interventions	One Intervention	Two or More Interventions	P
Number of patients	96	54	23
Mean number of interventions per year after AVF cannulation (± SE of mean)	0.755 ± 0.0971	1.37 ± 0.308	3.51 ± 2.20a	0.0152

When comparing: zero versus one intervention, P = 0.37; 0 versus two or more interventions, P = 0.004; one versus two or more interventions, P = 0.04.
