Observational studies examining outcomes after parathyroidectomy in patients with kidney transplants

Study	Country	Sample Size, PTx/Medical Treatment	Mean Age, yr	Women, %	Dialysis Duration before Kidney Transplant, mo	Median Time to PTx after Transplant, mo	Mean Duration of Follow-Up, mo	Study Period	Mean Serum iPTH, pg/ml	Mortality and Allograft Outcomes
Evenepoel et al., 2007 (60)	Belgium	90/1653	50.9	50.0	47.7	11.0	62.6 (From time of transplant)	1989–2004	107.1	Mortality difference; ↑ Cr 1.76–1.91 in first month after PTx; no long-term Cr difference
Ivarsson et al., 2015 (59)	Sweden	156/892	51.9	50.0	61.2	Not reported	76.9 (From time of PTx)	1991–2009	Not reported	No mortality difference

A consistent association with improved survival was observed in the dialysis population across studies. PTx, parathyroidectomy; iPTH, intact parathyroid hormone level; Cr, creatinine.
