Superseded Evidence Record
This page preserves the immutable v0.1.2 record. Its current successor is evt_NCT03152929_v3_v4_6b7b4c687f1b.
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 3 to version 4 for NCT03152929.
- The JSON Patch for this comparison has hash 34a95e3aa5b1ee22418eed3354f34ebf2bf3556c2400e76b8dee7d0d0052b47c.
- The active deterministic rule set hash was 318445b9ad266f51fd10ef378645c753ba7a098e3e4395c3c457750dc5f88d86.
- The deterministic triage label was high; before timing adjustment it was high.
- 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.
- A registry field under enrollment changed between ClinicalTrials.gov versions 3 and 4.
- The timing context for the from-version record was post_recruitment.
- The deterministic rules that fired were: enrollment_count_change.
- The changed JSON Pointer paths were: /protocolSection/statusModule/statusVerifiedDate, /protocolSection/statusModule/lastUpdateSubmitDate, /protocolSection/statusModule/lastUpdatePostDateStruct/date, /protocolSection/statusModule/resultsFirstSubmitQcDate, /protocolSection/statusModule/resultsFirstPostDateStruct, /protocolSection/designModule/enrollmentInfo/count, /protocolSection/outcomesModule/primaryOutcomes/1/timeFrame, /protocolSection/outcomesModule/primaryOutcomes/1/reviewUnit, /resultsSection/outcomeMeasuresModule/outcomeMeasures/1/timeFrame, /resultsSection/outcomeMeasuresModule/outcomeMeasures/1/reviewUnit, /annotationSection, /reviewUnit.
- An outcome path changed between versions 3 and 4 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 explains the enrollment change, and does the change affect interpretation of trial feasibility or power?
