| 1 Transplants during
the time period indicated in the last row of the table. |
| 2 Because different
cohorts are followed for each time period, it is possible for reported 3-year
survival to exceed 1-year survival. |
| 3 Based on U.S. graft
failure rates adjusted for recipient and donor characteristics as indicated in the Analytical Methods. |
| 4 A
p-value less than or equal to 0.05 indicates that the difference between the
actual and expected graft survival is probably real and is not due to random chance, while a p-value greater than 0.05 indicates that the difference could
possibly be due to random chance. |
| 5 Of
days expected to be included in the follow-up period, the percentage of days
covered by follow-up reporting by this center for these tranplants. A low percent may indicate a
non-representative sample from this facility for followup. This measures the possibility that events
such as failure have occurred without being reported, and it is not a measure
of compliance. |
| Based on data available as of 04/30/2002. Release at www.ustransplant.org on
