Literature searching and finding evidence

Once you have carried out a search, you need to screen your results for relevancy and then critically appraise and analyse the remaining articles.

Screening your results for relevance to your topic

Screening means reviewing the results from your literature search to determine which are relevant and can be included in your analysis/write-up.

You should only include results that meet your inclusion criteria - if something fails to meet any of the criteria, it should be excluded.

1. Go through the titles and abstracts of your results; don't be too strict in defining what meets your criteria at the beginning as titles and abstracts offer only limited information
2. Get the full-text of all studies which you have left and screen them more closely
3. Keep a record of any studies you have excluded as you may need to give details about these in the methodology section.

Identify the type of study you've found in order to select the appropriate critical appraisal tool.

Reading the abstracts should enable you to determine the type of study:
