Overall, there were very few graft failure events, which introduces greater fragility in the effect estimates. For example, there were only a total of 25 graft failure outcomes among the 786 participants over a mean of 37 months of follow-up in the ARB trials. Values and preferences. Kidney transplant recipients place a high priority on allograft survival. The SONG Kidney Transplantation (SONG-Tx) group was established to deter- mine which outcomes to measure in transplant trials.305 The SONG-Tx methodology included a Delphi survey that was completed by 461 patients or caregivers and 557 health pro- fessionals from 79 countries. They also held 3 consensus conferences in which patients and caregivers partici- Kidney allograft survival was unequivocally the dominant priority for patients, caregivers, and health pro- From the patient s perspective, there was a prevailing dread of returning to dialysis, and they focused on Preventing graft loss was the top priority, even over death, as the patients were more concerned with quality than quantity of life.305 The SONG-Tx work provides strong rationale for the use of interventions that will reduce graft failure. It is the opinion of the Work Group that most well-informed transplant pa- tients would have the same values and preferences for the avoidance of graft loss, as was evident from the SONG-Tx work. Thus, we believe that nearly all well-informed trans- plant patients would accept the tradeoffs of side effects of a CCB or an ARB in exchange for the possible bene t of pro- longed graft survival. Resource use and other costs. This recommendation as- sumes that an antihypertensive agent will be started for the treatment of high BP, and the guideline is to facilitate the decision on the choice of the agent. In most countries, generic CCBs and generic ARBs are inexpensive.
