Results indicated that in the univariate analysis, older age, being male, high cholesterol, serum uric acid, SGPT and bilirubin, hemoglobin >12.5 g/dl, ALP >300 U/L, serum phosphorus between 4.7-5.7 and 6.9-9.9 mg/dl, PTH <150 pg/dl, and albumin 4-6.3 g/dl had a significant effect on the survival of CKD patients when the event of interest (death) was considered as an outcome (P<0.25). This evidence concerns the gene PTH and chronic kidney disease.
