  • a Lifetime incidence of initiating ESRD care per 1000 persons.

  • b Observed stage-specific CKD prevalence is based on the NHANES, 1999–2006. We did not report the estimated prevalence of stage 5 due to the limited sample size in NHANES. ESRD lifetime incidence is based on data from the USRDS.

  • c Stage-specific CKD prevalence and ESRD incidence are based on simulation results from the base model with no race adjustments other than mortality, and with individual African-American risk factors (systolic BP, diabetes, albuminuria), and all three risk factors.
