Read and evaluate research articles

Read and evaluate research articles - introduction

Once you have found an article, you will also need to evaluate and rate it to determine if you can use it. Does the article answer your question? Is it of good scientific quality? These two videos walks you through what to think about when evaluating articles.

General tips for evaluating

  • Study design - Is it suitable for the research question?
  • Population size - can general conclusions be drawn?
  • Selection of participants in the study
  • Confounding factors/variables?
  • Bias?
  • Are conflicts of interest reported?
  • Is the financing of the study reported?

Evidence grading - templates

If you are assessing the quality of evidence in-depth, the GRADE method can be used. GRADE is short for Grading of Recommendations Assessment, Development and Evaluation, and the method is international standard in evidence-based practice.

The GRADE methodology framework covers:

  • Framing the question and important outcomes
  • Rating the quality of the evidence
  • Publication bias
  • How to deal with imprecision, inconsistency and indirectness
  • How to sum up and present evidence

Read more and start using the GRADE method  at the and the Grade Handbook.
