(+) = Not determined due to insufficient follow-up; fewer than this percentile have transplanted.
 
TT = Time to Transplant in days.
This table takes a cohort of waiting list registrations and shows how long it takes for 10%, 25%, and 50% (the median) of those patients to be transplanted. These tables take the point of view of a patient who has
just been registered on a waiting list and take into account all of the things that can happen to the patient
after wait listing, including receiving a transplant, being removed from the waiting list, and dying.
See Technical Notes chapter for a full discussion of the methods used for this table.
