This discussion on "evidence" makes me wonder if "inclusion" or "exclusion" criteria for a study are considered as "evidence" or are they something else?  For example, if "smokers" are to be excluded from a study, a definition of a "smoker" must exist, and then an interpretation of whether the subject satisfies the definition  must exist. In the  
"Fagerstrom Test for Nicotine Dependence", the subject is evaluated with respect to a series of questions, each of which requires its own "evaluation."  http://ww2.heartandstroke.ca/DownloadDocs/PDF/Fagerstrom_Test.pdf

Is there a definition for "evidence" that applies to any aspects of this situation, and if so, what would it be?

Of course. I just wanted to differentiate that an experiment is not an instance of any class called 'evidence' (in other words, an experiment 'is not' evidence). Instead, it should be associated with an 'evidence-role'.
