A product page may place a supplier description, a laboratory value and a research citation close together. That proximity can make them seem like one continuous body of evidence, even when the sources concern different materials and answer different questions.
Identify the speaker in each sentence
Mark whether a statement comes from the supplier, an analytical report, a research paper or the writer’s own interpretation. This is an attribution exercise before it is an assessment of whether the statement is persuasive.
The Singapore Statement on Research Integrity calls for conclusions based on critical analysis of evidence and for full, objective reporting of findings and interpretations. It is an international integrity statement rather than a regulatory document.Singapore Statement on Research Integrity (2010) (opens in a new tab)
Applied to a product-related explanation, this means that “the supplier describes”, “the report states” and “the authors observed” should retain their different subjects. Removing those subjects can accidentally imply independent confirmation.
Commercial origin does not make a statement automatically false, just as publication does not make every interpretation correct. Attribution allows the reader to evaluate the actual evidence instead of relying on the apparent authority of the page.
Map statements to the evidence they need
| Statement type | Evidence to inspect |
|---|---|
| A vial is labelled with a particular amount | The applicable product label or declaration |
| A tested sample produced an analytical result | The identified report and its method/result fields |
| A peptide affected an experimental endpoint | The original study and the relevant data |
| The commercial material matches the study material | A documented identity comparison, not the shared name alone |
Suppose a hypothetical page describes a peptide as “studied in cell signalling” beside a purity result. The research statement needs a paper describing the experiment; the purity statement needs evidence for the tested sample. Neither source automatically supports the other statement.
If the page then says that its own vial produced the published effect, that is an additional claim requiring an explicit connection to the study material. It cannot be inferred from a matching product name.
Keep the claim small enough to inspect. One sentence containing identity, quality, mechanism and expected outcome may need several sources and several qualifications.
Preserve the boundary between sources
A published study may use a specific sequence, salt form, preparation or model that differs from the commercial description. Before connecting the two, identify the relevant material details and any unresolved differences.
Do not use an analytical certificate as a citation for a biological mechanism unless it actually contains evidence addressing that mechanism. Likewise, a mechanistic paper generally cannot establish the content of a later supplier lot.
If a source is inaccessible, distinguish a statement about its title or abstract from a claim that its full methods and results were checked. The level of access affects what can honestly be attributed to your review.
Rewrite the paragraph around separate claims
A clear paragraph can first describe the supplied material, then summarise a relevant study with its model and endpoint, and finally explain whether the relationship between them is established or remains uncertain.
Place citations beside the clauses they support. A citation at the end of a long paragraph can be misleading when it supports only the final sentence or only the general background.
Check headings and captions as well as prose. A cautious paragraph can be undermined by a heading that presents an exploratory finding as an established property of every product carrying the name.
The reader should finish with a clear account of who said what and on what basis. That is more informative than a polished composite statement whose evidence changes halfway through the sentence.
