Modification of diet in renal disease estimated glomerular filtration rate (MDRD-4 eGFR) (P<0.001), serum phosphate (P=0.042), receptor activator of nuclear factor κappa-B ligand (RANKL) (P=0.001), parathyroid hormone (PTH) (P=0.014), and high-density lipoprotein (HDL)/cholesterol ratio (P=0.026) were independent predictors of CP accounting for 45% of variation. Here, PTH is linked to kidney disorder.
