AVF, arteriovenous fistula; CI, confidence interval; ESA, erythropoiesis-stimulating agents; ESRD, end-stage renal disease; STR, standardized transplant ratio.
Multivariable model was adjusted for all covariates shown in Table 4 as well as organ procurement organization region from which the dialysis facility resided. Markov Chain Monte Carlo multiple imputation used for missing covariate data (<2% of data).
