Appraisal tools

Appraisal tools

Using validated tools to critically appraise the evidence you find can help you to approach each paper in a standardised and systematic way. There are many critical appraisal tools and checklists that can help you ask the right questions when evaluating scholarly articles. 

Appraisal tools

Use checklists for thorough appraisal

RAMMbo

Use RAMMBo for quick appraisal

Glasziou et al. (2007) developed the RAMMbo mnemonic that allows you to quickly evaluate the trustworthiness of a research study. 

What should you look for?  Where could you find this information?

R - Recruitment

Were the participants in the study representative of the target population?

Were there enough participants to ensure that the study is valid?

 

Check the METHODS section or the DISCUSSION section.

A - Allocation

Were the participants randomly and blindly allocated to groups?

Were the groups similar at the start of the trial?

 

Check the METHODS section.

M - Maintenance

Were there any changes in the status of the control group and study group during the trial?

Apart from the intervention, were both groups treated in the same way?

 

Check the METHODS section.

 

Mbo - Measurement (blinding - objective measures)

Were the participants and/or researchers blinded to the intervention?

Were the outcomes measured objectively? 

 

Check the METHODS section or the DISCUSSION section.
