Evidence Synthesis Narrative Answer Generation

The evidence agent is asked to generate a plain-language summary for a 12-month all-cause mortality RWE study. The result record in the database stores: hr_point_estimate=0.67, ci_lower=0.54, ci_upper=0.83, p_value=0.0003. These …

The generated narrative states exactly 'HR 0.67' (or an equivalent decimal representation that rounds to 0.67 at two decimal places, per the system's declared rounding policy) along with '95% CI 0.54–0.83' and 'p=0.0003'. A mandatory post-generation numeric reconciliation step extracts each numeric…

Study RWE-2024-07 has three result records stored with overlapping field names: (A) primary endpoint — 90-day MACE, hr_point_estimate=0.71, p_value=0.002; (B) secondary endpoint — 90-day HF hospitalization, hr_point_estimate=0.58…

The narrative states HR=0.71, p=0.002 and explicitly identifies the source as result record A (primary endpoint: 90-day MACE). The citation in the narrative or its metadata contains the result record's unique identifier or endpoint label sufficient to distinguish it from records B and C. The agent …

Study PEDS-ABSENT-1 was conducted in adult patients aged 18 and older. The result database contains one primary result record for the adult population (HR=0.69, p=0.001) and two adult subgroup records (age 18–64 and age 65+). The…

The agent explicitly states that the study enrolled only adult patients (age ≥18), that no result record exists for pediatric patients in this dataset, and that providing a numeric estimate for children would require a dedicated pediatric analysis that has not been performed. The agent declines to …
