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 17 to version 18 for NCT04224272.
  • The JSON Patch for this comparison has hash f99a80f22c04de6d6019e0e9d723ac73375af7a7ac419fdd4b0afcbbfb60322a.
  • 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 late_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/2/description, /protocolSection/outcomesModule/primaryOutcomes/2/timeFrame, /protocolSection/outcomesModule/primaryOutcomes/2/reviewUnit, /resultsSection/outcomeMeasuresModule/outcomeMeasures/3/description, /resultsSection/outcomeMeasuresModule/outcomeMeasures/3/timeFrame, /resultsSection/outcomeMeasuresModule/outcomeMeasures/3/reviewUnit, /annotationSection.
  • An outcome path changed between versions 17 and 18 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

What source document explains this registry amendment, and does it change interpretation of the trial record?
