  1. aFacility N = 1874. Values presented as numbers (percentages) of facilities or means ± SDs of the percentage of facility patients. Using prescribed TT as an example, a mean of 70.9% of patients at facilities in the ≤75th measure percentile had a prescribed TT <240 min as compared to a mean of 73.7% of patients at facilities in the >75th measure percentile
  2. bThe 75th percentile represents 32.9% of facility patients with post-dialysis weight ≥ 1 kg above or below the prescribed target weight. Measure 75th percentile reflects the 75th percentile of the annual measure score, and facility data reflect the January 2012 cohort data
  3. cSignificance was assessed by Chi-square test for categorical variables and Student’s T-test for continuous variables
  4. dMean of the median household incomes. Income data was obtained from 2010 U.S. Census data based upon dialysis facility zip code
