Primary research is basically the publication of a single experiment. Secondary research or a review article looks at all the research on the topic. Per WP:MEDRS we go with review articles. If you use pubmed there is a button to the right that searches for just review articles on a topic. Cheers -- Doc James (talk · contribs · email) 13:14, 15 May 2011 (UTC)
