Actually, I have. I've seen your letter and I've read the articles.
In fact, I'd like to quote perhaps just one sentence from the latest one I've read, which was published in February 2012 in a reputable peer-reviewed journal, by Diaconu and colleagues:
Beyond the limited published reports on CCSVI intervention, much of the support for endovascular interventions in CCSVI currently comes from anecdotal patient self-reports posted on web sites, blogs, and chat rooms. Prospective randomized control trials will be necessary to fully understand the impact of endovascular treatment of CCSVI due to significant potential placebo effects, blinding will be of major importance in the randomized trials.
This is what we're doing.
