When studies disagree: cancer treatment and CCSVI as examples

This online CTV column goes a long way to explaining why a recent German/British study seemed to indicate that almost NO MSers had CCSVI: http://healthblog.ctv.ca/post/When-studies-disagree-cancer-treatment-and-CCSVI-as-examples.aspx. For MSers (or anyone), the bottom line is that we need to make sure that the methodology of the research and basis of comparison are valid if we are going to make intelligent decisions.  In the case of the German/British study, the methodology was so unorthodox that the researchers could in no way claim that they were searching for CCSVI - but yet they (or someone covering the story) did announce exactly that!
