CCSVI: Does it hold up?

CCSVI: Fact or Fiction?

When I saw Robert Zivadinov, MD PhD 2 weeks ago he was excited. He may have even have a greater reason to be excited.

When they looked at the preliminary data (first 500 patients) from the University of Buffalo Combined Transcranial and Extracranial Venous Doppler Evaluation (CTEVD) study, they found that when the 10.2% of subjects in which results were border line were excluded, the percentage of affected MS patients rose to 62.5%, compared to 25.9 percent of healthy controls.

These are promising results, but remember a few things that we discussed on previous blogs:

We need to prove the association (although 500 is a large number of patients) and then see whether association is equal to causation and then whether causation means that we can fix it after the fact.

I know it is hard, but patience is key ...
