PTx patients had 15.7% lower odds of premature death.
Levels of 10 mg/dL or higher and below 6 mg/dL predicted approximately 50% higher death risk in the 3 months after dialysis initiation.
Having 3 or 4 CKD-MBD markers in the danger zone more than doubled the chances of early death.
Death risk increased markedly once serum potassium values exceeded 5.5 mEq/L.
Evidence suggests decreased sodium absorption could be a contributing factor in at least some patients.
