All searches are a balance between choosing enough terms to be specific, but still give you helpful results

Combine terms with:

OR - for synonyms; words in the same column

AND - for different elements; words in different columns

(---) - to group words together

 

General Rules:

  • Always include terms for your Outcome, since you have to know what is being measured!
  • Use terms for BOTH your Intervention and Comparison for a very specific result (less articles), use only one for a broader result (more articles)
  • Don’t repeat terms unless you absolutely must!  (see how I use the words patient and hand below)

Specific/Narrow Search Statement:
