To the Editor: The retrospective cohort study by Dr Winkelmayer and colleagues1 suggested an inverse relationship between increasing altitude and all-cause mortality among US dialysis patients after adjusting for age, sex, and race in the dialysis population. Race and ethnicity have been shown to be associated with differences in all-cause and disease-specific mortality.2- 3 In addition to differences in risk factors and genetic influences, mortality rates reflect in part racial and ethnic differences associated with health care access and quality.4
