Critical Appraisal

Information and resources on how to assess the quality and relevance of articles

 

There are numerous tools to assist in evaluating the quality of published research.

  • Checklists provide an easy method to work through the methodological rigour of a paper.
  • Reporting standards give guidance to authors on how research should be conducted and reported. Read papers with a view to how well they meet these standards.
