Grey-literature source plan =========================== StatMedAnalysis | Original downloadable worksheet | 6 November 2026 Define a reproducible search of evidence outside conventional journal databases. How to use this worksheet Choose sources that plausibly contain relevant studies, such as registries, institutional repositories and conference collections. Record each source interface and search method, including browsing limits. Save export or retrieval evidence and distinguish inaccessible records from absent records. Save a working copy and keep the original blank version. Use public, hypothetical or aggregate information only; do not enter patient identifiers, credentials or confidential records. Keep source evidence in your approved project workspace. Mark unresolved text fields UNKNOWN or NOT REPORTED with a reason; never substitute zero for an unknown count.

Coverage limitation Response/evidence: _________________________________________________________ ___________________________________________________________________________ Hypothetical worked case A fictional conference website lists only the last three annual meetings. Searching that site does not establish that no relevant abstracts appeared earlier; the missing years need a separate retrieval plan. Decision rule and limitations Describe the actual coverage achieved. Do not call a grey-literature search comprehensive when source access or practical stopping limits leave known gaps.
