Thank you.
Having been a doctor filling out forms, I say in response to the question of who sets my regulations that it's the regulatory bodies. Then it's a question of who's going to pay what I expect to get paid, so I understand that part and I appreciate your comments.
There's one last thing I'll just ask Ms. Northey. I'm very interested in your concept of outcomes, and I know you sort of answered some of that in response to Ms. Lockhart. You talked about demographics, and a lot of the research might be more demographic in nature. I'm interested in knowing the parameters a little bit more in depth. Ms. Lockhart, you sort of answered my question, but in your outcomes, what sort of parameters are you looking for?
