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.

Return these fields exactly: duration, p_value, participants, primary_endpoint, result, source, study_id


[System] Extract structured facts only from the supplied text. Your complete response must be valid JSON, never a code fence or explanation. Emit every requested field exactly once at the requested level. Preserve spelling, punctuation, dates, amounts, and identifiers. Do not infer missing facts; represent unsupported requested values as null.
