Cochrane bias article


This article and the attached responses brought back many experiences
from my 32 years of working with clinicians in private practice as well as
the teaching environment.

Most physicians accepted me and my information as being highly
biased. However, I often observed that those who devaue the contributions
of the pharmaceutical industry were often using this bias issue to avoid
changes to their own approach to medicine and/or their political

I found the most dangerous bias issue in medical science was the one
demostrated by the individual who had come to the conclusion that he or
she had achieved a state of no bias. I suspect that these same individuals
will not be able to detect bias in the Cochrane artice.
