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-10144.
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.
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.
