Based on trust alone

Peer review and publication

Studies that are peer-reviewed and published may not be fair comparisons.

Even though a comparison of interventions has been published in a prestigious journal, it may not be a fair comparison and the results may not be reliable. Peer review (assessment of a study by others working in the same field by reviewing the methodology they used against the findings) does not guarantee that published studies are reliable. Assessments vary and may not be systematic.

BEWARE of claims based on where they are reported or how widely publicised they are alone.

REMEMBER: Always consider whether a comparison of the effects of an intervention is fair and whether the results are reliable.
