  • a BMI, body mass index; CKD, chronic kidney disease; HD, hemodialysis; PD, peritoneal dialysis.

  • b χ2 or ANOVA was used as appropriate.

  • c Proportion of patients with score <80% (signifying an inability to perform normal activities).

  • d Hemoglobin in g/dl can be converted to g/L by multiplying by 10.
