What is Evidence?

Some would consider it synonymous with "proof", "fact" or "knowledge".  Some define evidence as "grounds for belief". 

In Evidence-Based Medicine examination of the totality of evidence, rather than by selecting a limited sample of evidence is the best method for pursuing the truth.

Not all evidence is equal, and a set of principles can identify more vs less trustworthy evidence.

Evidence is necessary but not sufficient.  Clinical decision making requires the applicaiton of values and preferences.
