Case 56 — Selection bias in a self-reported forum sample · comparison exercise

Limit of the answer in “Selection bias in a self-reported forum sample”: “Discuss who chose to post, missing outcomes, unverifiable records…” 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: comparison. Make the basis of a comparison explicit before interpreting it.

Case 56 — Selection bias in a self-reported forum sample · comparison exercise

Summary draft for “Selection bias in a self-reported forum sample”: the answer addresses “Discuss who chose to post, missing outcomes, unverifiable records…”; the related point is “Such material can suggest questions but…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: comparison. Make the basis of a comparison explicit before interpreting it.

Case 56 — Selection bias in a self-reported forum sample · comparison exercise

Reader check for “Selection bias in a self-reported forum sample”: distinguish the discussion point “Discuss who chose to post, missing outcomes, unverifiable records…” from its proposed application. The thread offers a way to reason about the question, without adding a personal experience or a newly observed outcome. Review focus: comparison. Make the basis of a comparison explicit before interpreting it.

Case 57 — An evidence table with room for negative findings · comparison exercise

Clarification for “An evidence table with room for negative findings”: the point beginning “Include all prespecified outcomes where reported, null…” 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: comparison. Make the basis of a comparison explicit before interpreting it.

Case 57 — An evidence table with room for negative findings · comparison exercise

How can a reading table avoid highlighting only positive outcomes?

Review focus: comparison. Make the basis of a comparison explicit before interpreting it. Use the original answer fragment “Include all prespecified outcomes where reported, null…” as the discussion anchor; no new event or result is supplied.

Exercise RESEARCH-25905/57: address this question within its stated limits.

Case 57 — An evidence table with room for negative findings · comparison exercise

Method note for “An evidence table with room for negative findings”: use “Include all prespecified outcomes where reported, null…” 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. Make the basis of a comparison explicit before interpreting it.

Case 57 — An evidence table with room for negative findings · comparison exercise

Correction note for “An evidence table with room for negative findings”: retain the wording beginning “Include all prespecified outcomes where reported, null…” 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. Make the basis of a comparison explicit before interpreting it.

Case 57 — An evidence table with room for negative findings · comparison exercise

Summary draft for “An evidence table with room for negative findings”: the answer addresses “Include all prespecified outcomes where reported, null…”; the related point is “Separate the authors’ interpretation from the…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: comparison. Make the basis of a comparison explicit before interpreting it.

Case 58 — Comparing laboratory methods across years · comparison exercise

Two results were collected years apart with unknown method changes. What should be clarified?

Review focus: comparison. Make the basis of a comparison explicit before interpreting it. Use the original answer fragment “Ask whether assay, instrument, units or reference intervals changed…” as the discussion anchor; no new event or result is supplied.

Exercise RESEARCH-25905/58: address this question within its stated limits.
