CR was one of original designers of the registry, contributed to protocol writing, and submission of ethics application, and is chair of the registry steering group.
SI was one of original designers of the registry, contributed to protocol writing and submission of the ethics application, and is CI for the EVIDEM programme.
Thirty-two percent of comparisons performed demonstrated greater survivorship in the designer series compared to the registry, while 0% reported lower, and 68% demonstrated no difference.
That is enough to generate roughly a googol — 10 to the 100th power — of possible chains of up to 20 transplants if all of the pairs are compatible, said Rich Marta, the registry's senior software designer.
The group is also developing a product registry as a resource to help designers create cradle-to-cradle designed and certified collections, says Lewis Perkins, senior vice president.
Advantages of the use of UKA in anteromedial knee osteoarthritis compared to the use of TKA are addressed, followed by a formal review of the literature concerning survival analyses in both designer and non-designer series as well as registry data.
This may change as the registry is adopted by research sites that are not part of the designer group; there staff attitudes and clinical priorities may become more salient, as found in other registries [ 18].
