MEDLINE with Full Text and CINAHL both use specialized subject headings that allow for more precise searching, including the ability to limit your search to specific populations, interventions, outcomes, etc. MEDLINE uses MeSH (Medical Subject Headings) indexing with tree, tree hierarchy, subheadings and explosion capabilities. CINAHL uses subject headings unique to the database that use the same structure. The documents and links below can help you understand how to use these terms to improve your searches in these databases.
Traditionally when an article is described as a "research article" it is a primary source. The research is new and original. A secodary source would be a "review article." These types of articles describe previously conducted research. The article does not contain new and original research but shows the reader what had been accomplished by others.
