Abuse

Yes, another example of how the sloppy wording in the BNAC study press release encourages abuse.

In his second study, Dr. Zamboni performed venous angioplasty on MS patients with coexistent CCSVI (as defined in his first study). Although the percentage of patients who were symptom-free was reported to have increased after venous angioplasty, the actual annualized relapse rate for the entire group remained unchanged. These findings, which appear somewhat contradictory, are likely explained by a small number of people having more relapses after intervention and / or by differences in the period of observation before and after the procedure. Nonetheless, the relapse outcomes do not clearly support a clinical benefit of venous angioplasty.


His second study???? They are classifying the angioplasty as a second study? Also didn't I read in Zamboni's original study that the angioplasty failed 47% of the time? meaning re-occurrence of symptoms and relapses in those patients? they don't seem to mention that when the angioplasty was successful the disease did not progress.
