  • *Adjusted for age; sex; diabetes mellitus; CAD; CHF; CVA; COPD; liver cirrhosis; malignancy; systolic blood pressure; diastolic blood pressure; haemodialysis vintage; vascular access type; ESRD cause; cardiac index; haemoglobin, albumin, cholesterol, ferritin, sodium, potassium, ionised calcium, phosphate and parathyroid hormone levels; Kt/V; and ESA dosage.

  • CAD, coronary artery disease; CHF, congestive heart failure; COPD, chronic obstructive pulmonary disease; CVA, cerebrovascular accident; ESA, erythropoiesis-stimulating agents; ESRD, end-stage renal disease.
