I just checked the list of Doctors who might treat CIDP.. As far as I could tell, it is just that a list of Doctors who MIGHT treat CIDP. In my opinion there is no way to tell their experience in treating CIDP. The ratings cover everything that they treat.
I have checked the list of centers. And it is also just that a list. And then there is the Freedom Of Information Act. There is no nearby support group to Johns Hopkins Hospital. There is nowhere someone could get a first hand report on the doctors on that list. So it is just that a list. If there were ratings for CIDP treatment only, it would be a better list.
