Source: OPTN/SRTR Data as of October 1, 2010.

(+) = Not determined due to insufficient follow-up; fewer than this percentile have been transplanted.

WT = waiting time in days.

The waiting times in this table are lower than the Time to Transplant measures in Table 1.5. Waiting time

counts only time spent on the active waiting list before transplant. Time on the waiting list in inactive status

is not counted, and waiting time is censored when the patient is removed from the waiting list for any reason.

Patients who receive a living donor transplant are censored at transplant, and that transplant is not counted.

Patients who are inactive for the duration of their wait list registration are not included.

See Technical Notes for a full discussion of the methods used for this table.
