Description
When registrationKnown is true, test whether priorLabels contains outcomeLabel.
Evidence bookkeeping records identifiers, reported methods, source editions, and supplied support flags. A complete-looking citation or matching record is different from evidence of a claim's validity.
When registrationKnown is true, test whether priorLabels contains outcomeLabel.
When to use this tool
Use Trial Outcome Prior Label Token when you need a reproducible source or study-record consistency check.
How to use the tool and how it works
- Enter outcomeLabel, priorLabels, registrationKnown. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read listedPreviously, provenanceKnown. Inspect listedPreviously, provenanceKnown before interpreting the associated values.
When registrationKnown is true, test whether priorLabels contains outcomeLabel. Return provenanceKnown equal to registrationKnown.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| outcomeLabel | Outcome Label | Required. Text; maximum UTF-16 length 8192. |
| priorLabels | Prior Labels | Required. Array of text; maximum UTF-16 length 8192; maximum items 256. |

"input": {
"outcomeLabel": "pain",
"priorLabels": [
"pain",
"function"
],
"registrationKnown": true
},
"output": {
"listedPreviously": true,
"provenanceKnown": true
}
}Limitations and assumptions
- A false listedPreviously with unknown provenance does not prove an outcome was unregistered or selectively reported.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Read the original report and compare methods, outcomes, provenance, and uncertainty before assessing an evidence claim.
