What It Does
Clinical Intelligence Delivered as a Study
The reasons patients start, switch, and stop a therapy live in the clinical notes — not in claims or codes. LinQ Charts extracts those reasons at scale, across a nationally representative population, and delivers them as a scoped study your team can act on.
Answer the question structured data can't.
Switching drivers, discontinuation reasons, physician sentiment, and off-label rationale pulled directly from the clinical notes — not inferred from codes.
Your cohort, at national scale.
Define your population by diagnosis, line of therapy, geography, or payer. LinQ Charts runs the study across 85M+ EHR covered lives — not one health system.
Clinical evidence behind every finding.
Every answer is backed by the clinical detail and dates it was drawn from, so your team sees the source before they act on it.
Ask the next question without a new study.
Your purchased cohort stays available. Follow-up questions are answered from the same extraction — no re-fielding, no new spend.
How It Works
From Question to Decision-Grade Answer
Scope the study.
Step 1
You bring the clinical or business question. We define the cohort to your spec — diagnosis, line of therapy, geography, payer.
Extract from the notes.
Step 2
Clinical notes from EHR records run through validated LLM extraction with human clinical oversight, producing structured patient summaries at the cohort level.
Review the readout.
Step 3
Your study is delivered in weeks — source-linked patient summaries with the endpoints your question requires, backed by the clinical detail and timing behind every finding.
Keep asking.
Step 4
Follow-up questions are answered from the same study without re-fielding. Your cohort stays open.
Use Cases
NorstellaLinQ Can Answer the Questions Your Team Is Already Asking
LinQ Charts replaces the manual chart review. It answers the complex clinical and business questions hidden in patient charts, on any cohort you define, with the clinical detail behind every finding.
Switching and Discontinuation Drivers: Find the reasons patients switch or stop, pulled from the notes, to ground segmentation and messaging in documented clinical reality.
Physician Sentiment and Forward Treatment Planning: Surface the documented plan for a patient’s next months of care — a blind spot for most brand teams working from claims alone.
Off-Label Identification: Find patients treated off-label and the emerging rationale in their notes, useful at and after launch.

Frequently asked questions
Everything You Need to Know About LinQ Charts
LinQ Charts is a clinical intelligence capability that replaces the manual chart review for life sciences teams. Instead of abstracting charts by hand through a single health system — a process that takes ten weeks or more — LinQ Charts runs validated LLM extraction with human clinical oversight across 85M+ EHR covered lives and delivers a decision-grade study in weeks. Teams define the cohort themselves, and every finding is backed by the clinical detail and dates it was drawn from.
LinQ Charts uses validated LLM extraction with human clinical oversight to turn unstructured EHR notes into structured patient summaries across a nationally representative cohort. Teams define the population — by diagnosis, line of therapy, geography, or payer — and receive a scoped study with source-linked findings delivered in weeks. The approach covers 2.5B+ clinical notes and 350M+ unique patients, with every note tied to an NPI.
Structured claims data captures what happened to a patient — a diagnosis code, a dispensed prescription, a procedure. Clinical notes capture why it happened: the physician’s reasoning, a patient’s reported symptoms, treatment barriers, and the plan for future care. LinQ Charts is built to extract that unstructured context at scale across any cohort a team defines.
A traditional manual chart review conducted by nurses or CRAs through a single health system typically takes two and a half month or more. LinQ Charts delivers a comparable study output in weeks — across a nationally representative population rather than one system’s patient mix. Because the cohort stays open after delivery, follow-up questions are answered from the same extraction without re-fielding a new study.
LinQ Charts draws on 85M+ EHR covered lives, 350M+ unique patients, and 2.5B+ clinical notes, with every note tied to an NPI. Coverage spans oncology and non-oncology, with roughly a 60/40 academic-to-community split and up to seven years of longitudinal patient history.
