EMTREE EMTREE - Disease Link and Drug Link Terms Disease link terms and drug link terms are controlled terms frequently used with a medical or drug index term to indicate precise associations. They have been used in EMBASE since 1988. Search for these associations by using a hyphen between the index term and the link term or as independent terms. For example, the search cardiovascular-surgery in su retrieves records that are about surgical aspects of cardiovascular.
