We're referencing one of the recommendations of the “Do No Harm” document. Clearly that is one of the key areas that needs to be looked at, although it's one of several areas that need to be looked at. We're just promoting the notion that we've taken a very hard evidence-based look at what is the evidence around prescription guidelines internationally, in the U.S. where they clearly are ahead of us in the sense that they have some more experience on this.
I would defer to Dr. Selby in terms of the actual detail of what those guidelines would look like.
