Anoop, the question you asked is much harder to answer than it seems, and you will need to do quite a lot of reading to understand why "it is more complicated than that".
This article is a little old-fashioned now, but would be a good place to start:
http://www.bmj.com/content/312/7023/71.full
The best evidence is the most appropriate evidence. For treatments this comes from rigorous systematic reviews of high quality randomized controlled trials in which the outcomes are important to patients. This virtually excludes evidence from the basic sciences.
On second thoughts, a better place for you to start your reading would Ben Goldacre's book "Bad Science".
Hope this helps
Michael

Subject: Evidence Based Approach Question
I had a question about EBM. The definition of EBM is" The best available research evidence means evidence from valid and practically relevant research , often from the basic sciences ..."
So can we use just basic science to justify a treatment? Can anyone give an example please.
Thanks.
