  • aOR, adjusted odds ratio; 95% CI, 95% confidence interval.

  • a Model was adjusted for age, race, attributed cause of ESKD, atherosclerotic heart disease, other cardiac disease, cerebrovascular disease, peripheral vascular disease, diabetes, chronic obstructive pulmonary disease, cancer, insurance type, facility for-profit status, neighborhood race, neighborhood education, urban/rural, and state (model n=25,321).

  • b Model was adjusted for age, race, attributed cause of ESKD, atherosclerotic heart disease, other cardiac disease, cerebrovascular disease, peripheral vascular disease, diabetes, chronic obstructive pulmonary disease, insurance type, neighborhood race, neighborhood education, neighborhood poverty, urban/rural, and state (model n=9179).
