A practical framework for moving from an impressive abstract to a precise, balanced understanding of the evidence.
Begin with the study population. Record the participants’ relevant characteristics and the eligibility criteria, rather than assuming that a human study applies to everyone. Ask whether the paper concerns healthy volunteers, a particular condition or a specific clinical setting. This first question establishes the scope of the answer. If the population differs from the claim you are checking, the study may remain useful background while providing an indirect answer to that particular claim.
Write down the substance, formulation and relevant experimental description from the paper. A general ingredient name may not identify the studied intervention adequately. Check whether the commercial claim concerns the same item or an assumed equivalent. Keep combination products distinct from single substances. This step prevents a citation about a related molecule or preparation from being treated as direct evidence for something the researchers did not actually investigate.

- 3. What was the comparison?
- 4. What was the main outcome?
- 5. How large and how uncertain was the result?
- 6. What happened to participants and unwanted outcomes?
- 7. Who funded it, and has the question been revisited?
- Turn the seven answers into a short evidence note
