This is the twenty-second blog in a series of 36 blogs explaining 36 key concepts we need to be able to understand to think critically about treatment claims.
Even though a comparison of treatments 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) does not guarantee that published studies are reliable. Assessments vary and may not be systematic.
Critical appraisal tools (CATs) are commonly used by students and researchers alike, as a way of judging a study’s quality. In this blog, Dennis Neuen addresses the need to appraise these tools and has also collated a list of 12 CATs from all over the world.

This blog explains that claims about the effects of a treatment may be misleading if they are based on stories about how a treatment helped individual people, or if those stories attribute improvements to treatments that have not been assessed in systematic reviews of fair comparisons.

Reviews that do not use systematic methods may result in biased or imprecise estimates of the effects of treatments because the selection of studies for inclusion may be biased or the methods may result in some studies not being found. In addition, the appraisal of some studies may be biased, or the synthesis of the results of the selected studies may be inadequate or inappropriate.
Canada is in the midst of an opioid crisis and prescriptions have something to do with it. The question is, what? Lauren Gorfinkel discusses the need for new research which adequately investigates the ways in which prescription opioids enter and influence the lives of not only those who are prescribed opioids, but those that are not.
This is the twentieth blog in a series of 36 blogs explaining 36 key concepts we need to be able to understand to think critically about treatment claims.
A single comparison of treatments rarely provides conclusive evidence and results are often available from other comparisons of the same treatments. These other comparisons may have different results or may help to provide more reliable and precise estimates of the effects of treatments.
This is a Portuguese translation of the first in a series of 36 blogs explaining 36 Key Concepts we need to be able to understand to think critically about treatment claims. With thanks to Carlos Henrique dos Santos Oliveira and Cochrane Brazil for the translation. This blog explains that people often exaggerate the benefits of treatments and ignore or downplay potential harms. However, few effective treatments are 100% safe. Always consider the possibility that a treatment may have harmful effects.
Saul Crandon provides an overview of Case-control and Cohort studies: what are they, how are they different, and what are the pros and cons you need to consider in each study design.
In this blog, Sasha Lawson-Frost explores what moral values underpin or justify the practice of Evidence-Based Medicine, specifically in response to a recent article which stated “the policy side of evidence-based medicine is basically a form of rule utilitarianism”.

Systematic reviews take a long time to produce, and are often not up to date. In PLOS Medicine last month, a ‘living systematic review’ was proposed, to reduce the gap between evidence and practice.
Sean reviews ‘What is Evidence Based Medicine and Why Should I care?’, an article for students and healthcare professionals which covers Evidence-Based Medicine from first principles to medical statistics in the course of one free paper.
