This form is used to create a PICO framework-based search string suitable for systematic reviews or to easily identify all synonyms for a subject for comprehensive retrieval of all related content.
- In the main field, select the parameter you want to fill: Population, Intervention, Comparison or Outcome. You can type directly in these fields and use the suggested matching terms from Emtree.
Note that after you add a term, gray text appears beside it. Click this to add all the term’s synonyms to the search.
- Alternatively, start typing your search term under Search terms in Emtree on the right side of the form. Emtree suggestions are then displayed in their hierarchy positions. Click on term to view narrower terms in hierarchy.
