Essentially, the decision is based on what we refer to as the National Association of Medical Examiners. It's strictly an administrative-based definition. The SIDS concept, obviously, still exists.
As we move into the world of administrative data, as I mentioned earlier, we are consuming the information from the registries. It's a recommendation that came from the National Association of Medical Examiners. These changes were made to the coding at the registry level, and we receive this information. It's absolutely not to undermine the reality of SIDS; it's a conceptual definition that was actually made at some point there.
