Updated to 2010 dollars by using the medical care component of the Consumer Price Index. Each part of the two-part cost models estimated also included controls for age, age-squared, sex, race/ethnicity, education, region of residence, and each of the following comorbid conditions: diabetes, hypertension, cancer, arthritis, pneumonia, back pain, chronic bronchitis, and asthma. CI, confidence interval.
↵a Bootstrapped 95% CIs by using 1000 iterations.
↵b Calculated by using estimates of CKD prevalence for the population age 65 years or older to most closely approximate the Medicare population; prevalence estimated by using 1999–2004 NHANES data applied to 2010 Medicare enrollment data.
↵c Estimates are the product of the per person cost point estimates and the number of enrollees.
