Finding the Evidence

It is important when searching for evidence that search terms are referred back to your original PICO question. The process of finding evidence therefore follow three key steps: 

  1. Identify terms to fit your PICO question
  2. Look for secondary sources
  3. Search for primary sources

See our Searching Exercise page for a guide on how to complete this process.
