  • a Adjusted for sex, race, cause of ESRD, Medicaid status, and calendar year of ESRD onset and stratified by age categories.

  • b Adjusted for age category at incident ESRD, sex, race, cause of ESRD, Medicaid status, and calendar year of ESRD onset.

  • c Normal BMI is the reference category, with underweight defined as <5th percentile and obese defined as ≥95th percentile using the CDC age– and sex–standardized BMI z scores.
