  1. Population: in-center hemodialysis or hemodiafiltration (three times a week)
  2. aKt/V, nPCR, creatinine concentration, and %CGR were summarized in the patients with vintages of 2 years or more and receiving dialysis three times a week
  3. Note: Total number of each index was different from each other because response rate for the question was different in each other
  4. For the indices from age to percent creatinine generation rate (female), “mean ± S.D.” are shown
