How to critically appraise or what to look for.
When critically appraising evidence the following are the key areas to look at:
Is the information provided in the introduction logical and knowledgeable?
Is the research question of the study clearly stated?
Is the research methodology and research methods fully described?
Has the appropriate statistics being used in the analysis of the research findings?
Have all the subjects in the study being accounted for?
Are the conclusions provided well justified and valid?
Is the Cost/benefits discussed?
The acronym RAMMbo (Represent, Allocation/Adjustment, Maintain, Measured, Blind or objective) is used to guide the critical appraisal process to ask the key questions about potential bias in a study.
