Unfortunately, I'm not aware of it, and I'd be delighted to have the reference to explore it.
I recognize the urgency, Dr. Duncan. I also recognize the important link that you have made. MS is progressive, worsening, irreversible, and often debilitating. So in the face of treatments that are available and that may be still in their early stages in terms of the evidence base that is available, I understand that people with MS want to seek those treatments today or yesterday. It's an important value for the MS Society—let me just underscore this, a very important value for the society—that the decisions about managing and living with MS on a daily basis are decisions that belong to the people with MS, not to the society. Our role is to provide information, to provide guidance, and to assist people in making decisions.
