Note. NLM subject headings: https://www.nlm.nih.gov/mesh/. With regard to database selection: Though the material indexed in Medline is also included in NLM PubMed, the search algorithms can vary between interface providers, as can post-limit features and other options, and thus can yield slightly different results sets.
