(*) = Values suppressed due to small N (0 to 9).

(+) = Values not determined due to insufficient follow-up.

Cohorts are transplants performed during 1998-1999 for 3 month and 1 year; 1996-1997 for 3 year; and 1994-1995 for 5 year survival.

Patient survival follows patients from first transplant of this type until death. Counts for patient and graft survival are different because a patient may have more than one transplant for a type of organ.

Center volume = Center's yearly transplants performed during the base period, based on liver transplants.

Multi-organ transplants are excluded.
