The first question is: who was studied? A result obtained in cells, mice or in a small group of healthy adults cannot be automatically transferred to people with a specific disease. The population, intervention and outcome must correspond to the claim made.
Five questions before conclusion
- Is there a comparator? A placebo group or a relevant alternative shows better if the change comes from the intervention.
- Was the allocation randomized? Randomization reduces the risk that groups are different from the start.
- What was measured? A laboratory marker may be interesting, but it is not automatically a felt benefit or a reduced risk of disease.
- How large was the study? Small studies may produce unstable or random results.
- Who funded the research? A declared conflict of interest does not invalidate the study alone, but it must be considered and compensated for by independent replication.
Do not confuse association with causality
If two things appear together, we do not automatically know that one caused the other. Diet, exercise, sleep, existing treatments and participant selection may sometimes explain the observed differences.
A good signal: limits are declared
Solid articles describe what cannot be demonstrated. They do not transform an exploratory conclusion into a marketing promise. Look for limitations in the abstract and in the discussion section, not only the most spectacular result.
Sources and further reading
These references explain the subject and the limits of the evidence. A reference is not proof that a product treats a disease.
