  1. aFacility N = 1874. Values presented as numbers (percentages) of facilities or means ± SDs of the percentage of facility patients
  2. bThe 75th percentile of the target weight measure represents 32.9% of facility patients with post-dialysis weight ≥ 1 kg above or below the prescribed target weight. The 75th percentile of the ultrafiltration rate measure represents 20.3% of facility patients with UF rate ≥ 13 mL/h/kg and prescribed TT <240 min. Measure 75th percentile reflects the 75th percentile of the annual measure score, and facility data reflect the January 2012 cohort data
  3. cMean of the median household incomes. Income data was obtained from 2010 U.S. Census data based upon dialysis facility zip code
