Whether or not the statistic is out of date, my point still stands that most of these deaths aren’t due to rejection. The reason that lung transplants are needed in the first place is often the cause of other health issues. Some lung transplants are done for cystic fibrosis and the transplant isn’t a cure, as the new lungs will be damaged by the disease as well.

If you lose a leg due to diabetes you’ll likely have lower lifespan than if you lose a leg due to acute trama. Pointing to lung transplant survival as indicative of survival after a limb transplant is incorrect and disingenuous.
