Source: OPTN/SRTR Data as of May 1, 2007.

(-) = None in category.

These data include multi-organ transplants, other than kidney-pancreas, in which a deceased donor Expanded Criteria Donors (ECD) kidney was one of the organs transplanted.

Donors are divided into two mutually exclusive and complete categories. All donors meeting the criteria

for Expanded Criteria Donors for Kidney are classified as ECD, regardless of whether the kidneys were allocated under the ECD system. Non-ECDs include all other donors, including SCDs and DCDs.
