Research Designs In Mesh and Emtree: a Comparative Study of Coverage.

AMIA Annual Symposium Proceedings. Chicago, IL. November 2012:1594.

To aid retrieval of studies common to comparative effectiveness research (CER), we developed a terminology based on the local terminologies of several organizations. We compared coverage of the new terminology in MeSH and Emtree, and developed a crosswalk between the two controlled vocabularies. Patterns of coverage were similar and partial matches predominated. Negated or detailed terms were rarely matched exactly. For unmapped or partially mapped designs, records were retrievable if a substring in a design query matched the language of scientists.
