Incidence, risk factors and survival outcomes of post-transplant tertiary hyperparathyroidism in kidney recipients

Figure 1 Flow diagram of the study cohort selection. A total of 963 kidney transplant recipients transplanted between 2000 and 2020 were screened. Of these, 76 patients were excluded due to early graft loss or missing data (n = 54), primary hyperparathyroidism (HPT) (n = 2), calciphylaxis treated with cinacalcet (n = 1), or pre-transplant tertiary HPT (tHPT) (n = 19). The final analysis included 887 patients, of whom 125 developed post-transplant tHPT and 762 did not. HPT: Hyperparathyroidism; KTR: Kidney transplant recipient; tHPT: Tertiary hyperparathyroidism.
