2000 plus people have been de-stenosed after diagnosis with selective venography. This Dutch study is poor science and meaningless in size against 2000 real pwMS. Let's move on to real science not this rubbish.

I've seen people here at thisisms try to add up ballpark figures but it's never been evident there are any trustworthy numbers on how many people have had venous angioplasty for CCSVI. Confounding the situation even more is the consideration that a good number of people have been treated more than once and it's essential to be differentiate "number treated" from "procedures performed".

I agree with your points about the Dutch study but it's also important to point out that, in kind, there isn't "real science" and only "rubbish" to compare it to.
Even if it were true that 2000 people have been treated with venous angioplasty for CCSVI, proper studies haven't been done capable of proving that any of them were "successful" and more than that, no one has officially kept track of the number treated or percentage of patient claimed results or the number of positive and negative results claimed but it is certain that a sizable percentage are having less than positive results.
Point is that if there were 2000 treated so far, it's not fair nor accurate to throw that number around as if the entire number were positive results.
Worse, the above situation you refer to by and large involves ONLY people who have sought a CCSVI diagnosis and treatment who, by a preponderance, have MS. With it in mind that the most elementary factor of disease research is comparing those with disease to those without disease in order to identify and hopefully rectify the differences, it's essential to again stress that it's yet to be convincingly proven with equal testing methods that CCSVI is unique to those with MS and is uncommon in "normals".
