  • Parameters included in the model: FGF-23pre, serum albumin-corrected calcium, phosphorus, PTHpre, calcidiol, calcitriol alkaline phosphatases, and eGFR. PTH and FGF-23 were Ln-transformed for regression analyses. Only parameters univariately associated at P ≤ 0.2 for at least one time point are mentioned in the table.
