Looking at a subset of 605 patients with complete information on calcium and PTH at the time of kidney transplantation and at the 2 year follow up where the rates were similar: no HPT was present at the time of transplantation in 7.1% (n = 43), secondary HPT in 39.3% (n = 238) and secondary HPT with hypercalcemia in 53.6% (n = 324) of patients before KT. Here, PTH is linked to Hypercalcemia.
