a
AVF, arteriovenous fistula; AVG, arteriovenous graft; CHF, congestive heart failure; CVC, central venous catheter; CVD, cardiovascular disease; IHD, ischemic heart disease; PVD, peripheral vascular disease.
b
P = 0.0001, χ2 test of two-sample proportions comparing AVG group with any fistula group.
c
P = 0.006, χ2 test of two-sample proportions comparing CVC group with any fistula group.
d
P = 0.0018, two-sample t test comparing CVC group with any fistula group.
