Case 18 — A literature note that separates hypothesis from observation

A paper proposes a mechanism but the summary describes it as an established clinical effect. How can the note be corrected?

Exercise RESEARCH-24205/18: address this question within its stated limits.

Case 18 — A literature note that separates hypothesis from observation

State the study design and what was actually measured before discussing the proposed mechanism. Keep speculation explicitly labelled and avoid translating it into treatment advice.

Case 18 — A literature note that separates hypothesis from observation

Clarification for “A literature note that separates hypothesis from observation”: the point beginning “State the study design and what was actually measured…” 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 — A literature note that separates hypothesis from observation

Method note for “A literature note that separates hypothesis from observation”: use “State the study design and what was actually measured…” 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 — A literature note that separates hypothesis from observation

Limit of the answer in “A literature note that separates hypothesis from observation”: “State the study design and what was actually measured…” 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 — A literature note that separates hypothesis from observation

Correction note for “A literature note that separates hypothesis from observation”: retain the wording beginning “State the study design and what was actually measured…” 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 — A literature note that separates hypothesis from observation

Summary draft for “A literature note that separates hypothesis from observation”: the answer addresses “State the study design and what was actually measured…”; the related point is “Keep speculation explicitly labelled and avoid translating…”. 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 — Correlation in a small observational dataset

Report sample size, potential confounders and measurement uncertainty. Association does not identify direction or causation, and exploratory results need independent evaluation.

Case 19 — Correlation in a small observational dataset

Two variables move together in a small sample. What would a careful discussion acknowledge?

Case 20 — Units and scale: prevent a silent comparison error

Two figures use different units and one axis is logarithmic. How should a comparison be documented?
