  1. Calcium was adjusted for serum albumin according to the equation: corrected Ca = measured Ca + (4.0 - serum albumin in g/dL)
  2. Urea nitrogen, creatinine, and hematocrit were excluded in crude analysis because of a strong association with normalized PCR, creatinine generation rate, and hemoglobin, respectively
  3. Cumu. mean predia. β 2 -M cumulative mean predialysis β2-microglobulin, PCR protein catabolic rate. WBC white blood cell, DW dry weight
