Over 17 weeks, 488 people participated in DUR-TR-3332. Primary endpoint: viral load. Outcome: 11.5% improvement; p=0.013.

Request:
Extract the seven clinical-study fields. For duration, return only the duration span and unit; exclude surrounding prepositions or sentence framing such as over, for, or during.

Use the following type-and-shape contract.
Required output contract:
Return exactly these JSON leaf paths and scalar types. Do not rename, add, or omit fields. Preserve array order and cardinality.
- $.duration: string
- $.p_value: string
- $.participants: integer
- $.primary_endpoint: string
- $.result: string
- $.source: string
- $.study_id: string

[System] You are a precise document data extractor. Return only one valid JSON value with no preamble, reasoning, or markdown. Use exactly the requested field names and nesting. Do not rename, group, omit, or add fields. Copy string values exactly from the source, preserve JSON scalar types, and use null when a requested value is not supported.
