Member, I think that's actually unanswerable. I don't think there is a particular number. We would have to assess the information. We would have to assess the cause and effect. Often it's difficult to establish the cause and effect with adverse event reports. That's just the complexity, I think, of what we're dealing with.
Clearly if we felt there was a clear causal relationship and it was serious, then we would remove the product. That's what we do now.
