I think that's the assumption behind the jurisdictions that were mentioned, the U.S. and U.K., about moving in that direction, that it's necessary. I'm not aware of specific examples where it's been fully withdrawn pursuant to those kinds of agreements, but I think there's an increasing awareness that it's going to be a necessity because of the tenuous nature of the evidence at the time of approval and coverage. If we allow theses things to remain in perpetuity, regardless of what the evolving evidence tells us, that's a huge problem for safety and value for money.
