Claims Supported
- TrialDiff compared ClinicalTrials.gov record version 8 to version 9 for NCT03535506.
- The JSON Patch for this comparison has hash b0b377c7df2d5c4c0e57a1fba4d88d08e73ed3a2bdfce18162f0ef3ae67c46f2.
- The active deterministic rule set hash was fc87f4f0a74bc789dbe4ba85893c2c96f55db62c22970be4e991288104291621.
- The deterministic triage label was low; before timing adjustment it was low.
- The triage label is uncalibrated metadata, not a validated review-priority finding.
- The patch satisfied these deterministic event-class predicates: outcome_edit_cooccurs_with_results_posting.
- The timing context for the from-version record was post_recruitment.
- The changed JSON Pointer paths were: /protocolSection/statusModule/statusVerifiedDate, /protocolSection/statusModule/lastUpdateSubmitDate, /protocolSection/statusModule/lastUpdatePostDateStruct/date, /protocolSection/statusModule/resultsFirstSubmitDate, /protocolSection/statusModule/resultsFirstSubmitQcDate, /protocolSection/statusModule/resultsFirstPostDateStruct, /protocolSection/outcomesModule/primaryOutcomes/0/measure, /protocolSection/outcomesModule/primaryOutcomes/0/description, /protocolSection/outcomesModule/primaryOutcomes/0/timeFrame, /protocolSection/outcomesModule/secondaryOutcomes/0/measure, /protocolSection/outcomesModule/secondaryOutcomes/0/description, /protocolSection/outcomesModule/secondaryOutcomes/0/timeFrame, /protocolSection/outcomesModule/secondaryOutcomes/1/measure, /protocolSection/outcomesModule/secondaryOutcomes/1/description, /protocolSection/outcomesModule/secondaryOutcomes/1/timeFrame, /protocolSection/outcomesModule/secondaryOutcomes/2/measure, /protocolSection/outcomesModule/secondaryOutcomes/2/description, /protocolSection/outcomesModule/secondaryOutcomes/2/timeFrame, /hasResults, /resultsSection, /documentSection.
- An outcome path changed between versions 8 and 9 in a patch that also carried a hasResults or resultsSection co-occurrence signal.
Claims Not Supported
- That the amendment was scientifically unjustified.
- That the change constitutes misconduct or wrongdoing.
- That sponsor intent can be inferred from this registry change.
- That the change caused or altered the trial's results.
- That the change was or was not disclosed in a manuscript.
- That TrialDiff determines regulatory compliance or non-compliance.
- That co-occurrence with results posting proves the outcome edit was harmless, administrative, or substantively benign.
- That event-class membership is a validated global review-priority ranking.
Neutral Review Question
