Case 50 — Correlation in a small observational dataset · comparison exercise
Two variables move together in a small sample. What would a careful discussion acknowledge?
Review focus: comparison. Make the basis of a comparison explicit before interpreting it. Use the original answer fragment “Report sample size, potential confounders…” as the discussion anchor; no new event or result is supplied.
Exercise RESEARCH-09246/50: address this question within its stated limits.

Case 50 — Correlation in a small observational dataset · comparison exercise
Method note for “Correlation in a small observational dataset”: use “Report sample size, potential confounders…” 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 50 — Correlation in a small observational dataset · comparison exercise
Limit of the answer in “Correlation in a small observational dataset”: “Report sample size, potential confounders…” 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 50 — Correlation in a small observational dataset · comparison exercise
Correction note for “Correlation in a small observational dataset”: retain the wording beginning “Report sample size, potential confounders…” 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 50 — Correlation in a small observational dataset · comparison exercise
Summary draft for “Correlation in a small observational dataset”: the answer addresses “Report sample size, potential confounders…”; the related point is “Association does not identify direction or causation, and…”. 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 50 — Correlation in a small observational dataset · comparison exercise
Reader check for “Correlation in a small observational dataset”: distinguish the discussion point “Report sample size, potential confounders…” 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 51 — Units and scale: prevent a silent comparison error · comparison exercise
Clarification for “Units and scale: prevent a silent comparison error”: the point beginning “Record the original units and axis transformation, show any conversion…” 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 51 — Units and scale: prevent a silent comparison error · comparison exercise
Two figures use different units and one axis is logarithmic. How should a comparison be documented?
Review focus: comparison. Make the basis of a comparison explicit before interpreting it. Use the original answer fragment “Record the original units and axis transformation, show any conversion…” as the discussion anchor; no new event or result is supplied.

Case 52 — Reading an abstract without skipping the methods · comparison exercise
A strong abstract conclusion is being discussed without the study methods. What should the reading note cover?
Review focus: comparison. Make the basis of a comparison explicit before interpreting it. Use the original answer fragment “Identify population, design, comparator, outcome…” as the discussion anchor; no new event or result is supplied.
