  • Model A examined the unadjusted effect of patient race on receipt of nephrology care. Model B added the remaining patient demographic and clinical variables to model A. In model C, patient-level socioeconomic characteristics were added to model B. In model D, area-level socioeconomic status markers were added to model C. Finally, in model E, zip code–level racial composition was added to model D.
