A review cites another review for a claim about an experiment. How can the evidence chain be checked?
Reply scope: address the opening question, explain the supporting record or reasoning, and state the limit of the answer.
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.
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.
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.
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.

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.
