Superseded Evidence Record

This page preserves the immutable v0.1.2 record. Its current successor is evt_NCT05549505_v9_v10_1d420ffdb4b8.

Severity is deterministic, reproducible, uncalibrated triage metadata, not validated review priority or proven wrongdoing. This page states what the registry evidence supports and what it does not support.

Claims Supported

  • TrialDiff compared ClinicalTrials.gov record version 9 to version 10 for NCT05549505.
  • The JSON Patch for this comparison has hash 098370f38adbb892660901329a3b4a4524bf708773debab65bef32ebac5830e1.
  • The active deterministic rule set hash was 318445b9ad266f51fd10ef378645c753ba7a098e3e4395c3c457750dc5f88d86.
  • 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/resultsFirstSubmitQcDate, /protocolSection/statusModule/resultsFirstPostDateStruct, /protocolSection/outcomesModule/primaryOutcomes/0/description, /protocolSection/outcomesModule/secondaryOutcomes/1/description, /protocolSection/outcomesModule/secondaryOutcomes/1/reviewUnit, /protocolSection/outcomesModule/secondaryOutcomes/3/description, /resultsSection/outcomeMeasuresModule/outcomeMeasures/0/description, /resultsSection/outcomeMeasuresModule/outcomeMeasures/0/measureCategoriesReviewUnit, /resultsSection/outcomeMeasuresModule/outcomeMeasures/2/description, /resultsSection/outcomeMeasuresModule/outcomeMeasures/2/reviewUnit, /resultsSection/outcomeMeasuresModule/outcomeMeasures/4/description, /resultsSection/adverseEventsModule/timeFrame, /resultsSection/adverseEventsModule/description, /annotationSection.
  • An outcome path changed between versions 9 and 10 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
