Purpose. This framework supports critical reading. It is not medical advice and does not recommend a product.
1. What question did the study ask?
A mechanism study, formulation study and clinical trial do not seek the same answer. Before reading the result, identify the population or model, intervention, comparator and measured outcome.
Principle. A reliable conclusion stays within the boundaries of the question that was actually studied.
2. Which model produced the result?
Cells can isolate mechanisms, animals show responses in a whole organism and human trials examine a defined population. Moving from one level to the next requires new evidence, not merely stronger wording.
3. Is the source primary and complete?
A trial registry describes a protocol, a full publication explains methods and a press release presents selected findings. A commercial summary may guide readers but should not replace those sources.
Look for the original document, publication date, authors, funding and potential conflicts of interest.
4. How large is the result in practical terms?
Inspect absolute values, uncertainty, withdrawals and duration. A group average can hide wide variation between participants. Statistical significance does not guarantee practical importance.
5. What is the regulatory status?
A molecule can be under study without being approved. Positive findings are neither authorisation nor individual advice. Check current status with the relevant authority or registry at the time of reading.
6. Does the evidence concern this exact product?
Even when a molecule has been studied, a seller must still establish the identity and quality of its own batch. A scientific publication and a batch certificate answer different questions.
A careful conclusion therefore separates the molecule’s theory, published results and evidence attached to the physical product.
