A strong significant correlation was found between HPT type, PTH levels and graft loss at every time point. Mean PTH exposure remained strongly and independently associated to long term graft loss (OR 3.1 [1.4\u20137.1], <jats:italic>p<\/jats:italic>\u2009=\u20090.008). THPT was independently associated with graft loss at month-1 when compared to HPT absence and at every time point when compared to SHPT. No correlation was found with RTx-p death. Discriminatory analyses identified the best mean PTH cut-off to predict long-term graft loss to be between 88.6 and 89.9\u2009pg\/mL (AUC\u2009=\u20090.658). Cox regression analyses highlighted that THPT was strongly associated with shorter long-term graft survival at every time-point
