Data are derived from the Centers for Medicare and Medicaid CCW 20% sample. Source of coverage, Medicare eligibility, and ESRD status were ascertained in December 2007. Each observation is weighted by 5 to give population estimates. Unless otherwise indicated, values are percentages. AI/AN, American Indian/Alaska Native; LIS, low-income subsidy; PI, Pacific Islander.
Differences between estimate for ESRD population and non-ESRD population significant at the P<0.05 confidence level.
Differences between estimate for ESRD population and non-ESRD population significant at the P<0.05 level after Bonferroni correction.
Significant deviations from the expected value for the population in the distributions of beneficiary characteristics within coverage groups based on chi-squared tests (P<0.05).
