^a hs-CRP, C Reactive Protein

^b P, Serum Phosphate

^c Dialysis vintage, time since the initiation of dialysis.

Model 1: adjusted for serum phosphate, ionized serum calcium, and hs-CRP. (R² = 0.46)

Model 2: adjusted for model 1 plus age, dialysis vintage, serum ferritin, iPTH, ferritin, 25 (OH) D, and 1,25 (OH) ₂D. (R² = 0.54)

Model 3: adjusted for model 1 plus calcium dialysate, the use of calcium-based binders, calcium-free binders, paricalcitol, cinacalcet and erythropoietin (R² = 0.46)
