  • Data are relative excess risks (95% confidence intervals). A relative excess risk of 0.73 (for example) means that the excess risk of ESRD-related mortality in any given calendar year was 27% lower than it was 5 years previously (or 0.73 times the risk 5 years previously). Model fit was assessed using the chi-squared test for goodness of fit, which showed no evidence of significant lack of fit.

  • a The unadjusted model included age and a calendar year by age interaction. Both adjusted models also included sex, race, socioeconomic status quartile, and insurance status at ESRD initiation. The model shown in column 3 also included primary disease; the model shown in column 4 also included number of comorbidities at ESRD initiation.

  • b The unadjusted model included age (time dependent) and RRT modality (time dependent) as well as the following interaction terms: calendar year by age, calendar year by RRT modality, RRT modality by age, and calendar year by age by RRT modality. Both adjusted models also included sex, race, socioeconomic status quartile, and insurance status at ESRD initiation. The model shown in column 3 also included primary disease; the model shown in column 4 also included number of comorbidities at ESRD initiation.
