Missing study-results investigation =================================== StatMedAnalysis | Original downloadable worksheet | 6 November 2026 Investigate outcomes or analyses mentioned in a protocol but absent from a report. How to use this worksheet Compare registry, protocol, analysis plan and published report versions. Match outcomes by definition and time point rather than label alone. Record whether a result is missing, changed or incompletely reported. Seek clarification and assess how selective availability could affect the synthesis. 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.

The reviewer records the unmatched outcome and investigates the change instead of assuming the later result was null. Decision rule and limitations Do not infer the direction of an unreported result. Document the discrepancy and its implications for availability bias using the appropriate assessment framework.
