I know, for example, that some patients came to Health Canada saying that they had tests demonstrating that it could not be anything else other than thalidomide, but there is no test that could prove it was thalidomide. If that's the case, I think we are quite close to some sort of certainty. It can't be anything else but you cannot demonstrate that it is, so we're very close. It's a question of semantics, if I'm not mistaken here.
I'll forward the question to the Health Canada people. How many cases of that nature, of that close proximity to a diagnosis, have you had to decline?
