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 …

A narrative for Study XR-441 was generated and cached at T=0 using result record version 1: HR=0.72, 95% CI [0.52, 0.99], p=0.04 (statistically significant). At T+2h an analyst corrected an erroneous exclusion criterion in the co…

The agent detects that the cached narrative's embedded result_version tag does not match the current result record version in the database, refuses to serve the v1 cache, and either (a) regenerates the narrative from the v2 result record and serves HR=0.81 p=0.09 with a note that the study was reco…
