Case 18 — Reference management: distinguish primary and secondary sources

Locate the primary study and confirm that it measured the claimed outcome. Record when only a secondary account was accessible and avoid presenting it as direct verification.

Case 18 — Reference management: distinguish primary and secondary sources

A review cites another review for a claim about an experiment. How can the evidence chain be checked?

Exercise RESEARCH-30406/18: address this question within its stated limits.

Case 18 — Reference management: distinguish primary and secondary sources

Clarification for “Reference management: distinguish primary and secondary sources”: the point beginning “Locate the primary study and confirm that it…” belongs to the question as written. It should not be read as a report that a new check, purchase or experiment has been completed. Review focus: scope. Keep the stated question separate from any broader claim.

Case 18 — Reference management: distinguish primary and secondary sources

Method note for “Reference management: distinguish primary and secondary sources”: use “Locate the primary study and confirm that it…” as a row heading in a proposed working record. Put the statement, its supporting source or measurement, and any unresolved detail in separate fields. This proposes a format; it supplies no additional evidence. Keep the stated question separate from any broader claim.

Case 18 — Reference management: distinguish primary and secondary sources

Limit of the answer in “Reference management: distinguish primary and secondary sources”: “Locate the primary study and confirm that it…” is an excerpt from the discussion, not an independent verification. A reader needs the relevant original material before treating an interpretation as established. Review focus: scope. Keep the stated question separate from any broader claim.

Case 18 — Reference management: distinguish primary and secondary sources

Correction note for “Reference management: distinguish primary and secondary sources”: retain the wording beginning “Locate the primary study and confirm that it…” in the record. If later material changes it, add the date, the changed wording and the source for that change; do not invent a completed correction here. Keep the stated question separate from any broader claim.

Case 18 — Reference management: distinguish primary and secondary sources

Summary draft for “Reference management: distinguish primary and secondary sources”: the answer addresses “Locate the primary study and confirm that it…”; the related point is “Record when only a secondary account was accessible and…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: scope. Keep the stated question separate from any broader claim.

Case 19 — Selection bias in a self-reported forum sample

Discuss who chose to post, missing outcomes, unverifiable records and changes in reporting over time. Such material can suggest questions but cannot establish population-level rates.

Case 19 — Selection bias in a self-reported forum sample

A collection of forum reports is being treated as a representative sample. What limitations belong in the note?
