Statistical Narrative Agent

H1ST-AI-STAT-004 · Task 3.4

The blank page shouldn't cost you a week

The hardest part is the blank page, and the scariest part is trusting a draft you can't check. This agent uses an LLM supplied with your study context, tables, and analysis datasets to draft results narratives and stakeholder summaries where every figure traces back to a source output. Biostatisticians and writers get past the blank page with the numbers grounded and every claim reviewable.

The grind you know

The blank page shouldn't cost you a week

Turning a stack of tables into readable results text is slow, painstaking work, and every freehand paragraph carries the quiet risk of a number drifting from its source output. You have been burned by ungrounded AI writing too, which is why automation often costs you as much time fact-checking as it saves, or you avoid it altogether.

How it works

  1. 1

    Provide context and outputs

    Supply the study synopsis, TLFs, and datasets that the narrative should be written from.

  2. 2

    Draft with grounding

    The LLM generates narrative and summary text drawn strictly from the supplied outputs, tagging each figure to its source.

  3. 3

    Review and finalize

    A biostatistician reviews the grounded draft, resolves flagged assumptions, and remains the author of record.

Capabilities

What it takes off your plate

Grounded drafting

Generates narrative text only from supplied TLFs and datasets, so every reported number has a traceable source.

Results narratives

Drafts efficacy and safety results sections aligned to the ICH E3 results structure.

Executive summaries

Condenses detailed results into stakeholder-ready summaries for internal and governance reporting.

Source traceability

Links each stated figure back to its originating table or listing for rapid statistician verification.

What you get

  • Draft study and results narratives
  • Executive summaries for stakeholder reporting
  • Source-to-statement traceability references
  • Reviewer-ready draft with flagged assumptions

In practice

What this looks like on a real study

Where the agent shows up in the day-to-day of a live trial — the moments the grind usually lives in.

Past the blank page on results text

You're staring at a stack of efficacy tables and an empty results section. The agent drafts the narrative to the ICH E3 results structure using only your supplied TLFs, so you edit grounded prose instead of starting cold.

Verifying a number in seconds

A reviewer wants to confirm a response rate in the draft. Because every figure is tagged to its source output, you trace the statement straight back to the originating table rather than re-checking it by hand.

An ambiguous source output

A table is incomplete where the narrative needs a value. Instead of guessing, the agent flags the assumption for human resolution, keeping the biostatistician the author of record and in control of the claim.

Peace of mind

Built to the standards inspectors expect

Every output is generated inside a validated, audit-ready platform, kept under human-in-the-loop control, and mapped to the regulatory and CDISC standards this agent supports.
