Figure 1: Flow diagram of study population.
**The sum of these patients equals the number of people who were on the waiting list for a second lung transplant (N=818). 254 out of 818 (31%) patients died while waiting for re-transplant. Note: it is possible that some of the 408 individuals who died without a transplant may have been missing a waiting list date thus the deaths on the waiting list may be underestimated.
The sum of the individuals in the orange boxes (218+177=395) equals the total number of re-transplant recipients.
