Estimates of the incidence of chronic rejection in various solid organ allografts

Allograft	Incidence of OA at 5 Years	References
Heart	25% – 60%	[1], [2], [3]
Heart-Lung	8% – 20% (OA)	[1], [4]
	50% – 60% (OB)	[1], [5], [7], [8]
Lung	28/45% (single/double lung)	[7]
Liver	3–17%; 10% and decreasing	[9], [10]
Pancreas alone	30–70%*(late graft loss)	[11]
Pancreas and kidney	20–40%*	[11]

^*Estimates based on graft survival rates after one year, with the assumption that most late graft failures are due to CR.
