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

Record format: question; proposed response; source or method; limitation. Use a dated correction only if the underlying wording or evidence changes. Record RESEARCH-16744.

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.

Clarification for “Selection bias in a self-reported forum sample”: the point beginning “Discuss who chose to post, missing outcomes, unverifiable records…” 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 “Selection bias in a self-reported forum sample”: use “Discuss who chose to post, missing outcomes, unverifiable records…” 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.
