Table 1. Variables entered into the multiple logistic regression models to derive propensity scores for the placement of arteriovenous fistula (AVF) versus catheter and AVF versus arteriovenous grafts (AVG)

VariableCatheter ORa (95% CI)AVG ORa (95% CI)
ESRD, end-stage renal disease; BMI, body mass index; ACT, Australian Capital Territory; ANZDATA, Australian and New Zealand Dialysis and Transplant Association.
a Adjusted for age, gender, race, BMI, late referral, primary renal disease, cigarette smoking, diabetes mellitus, coronary artery disease, peripheral vascular disease, cerebrovascular disease, lung disease, hypertension, geographic location, and ANZDATA survey at entry.
b Versus white patients.
c Versus nonsmokers.
d Versus no diabetes.
e No patients in this state had a AVG.
