Source check
Check the source behind every key message.
Every key message your materials make about a medicine should rest on a source, such as the prescribing information or a published study. Juncture checks that there is one, that it supports the message, that the numbers match, and that it is the current version. A message that still cites the version with the old 20 mg dose is caught.
The prescribing information, which people in pharma call the label, is the official document a regulator approves for each medicine: the FDA in the US, the European Commission or a national agency in Europe, the MHRA in the UK.
Varigel lowered blood pressure by 12 mmHg at 8 weeks compared with placebo.
Four checks on each source, plus the kind of source. The passage that supports the message is found and highlighted in the source.

What it checks
Four checks on the source behind every message.
Each check returns a result with its proof: the passage it found, the numbers it compared, the version it looked up. Reviewers see the reason along with the result.
There is a source
Does the message cite anything?
A message that states something checkable and cites nothing is flagged first, before anything else is weighed.
It supports the message
Does the cited part say what the message says?
Juncture reads the part of the prescribing information the message cites, matches it to the message by meaning and finds the passage that supports it.
The numbers match
Are the figures in the source?
Each number in the message is compared with the cited part, so a figure, a time point or a rounding the source does not state is caught.
It is the current version
Is the source up to date?
The current prescribing information is looked up live on the regulators' public websites: EMA and emc for Europe and the UK, DailyMed and openFDA for the US. A source on an older version is flagged.
The score
One score per message, and one view of all your messages.
The four checks and the kind of source add up to a score from 0 to 100. Every checked message rolls up into one view, so the weak sources become a to-do list.
The right kind of source
Some sources carry more weight than others. For a message the prescribing information can support, it is the expected source and ranks above a journal article. The score reflects which one the message cites. Reviewers call this the evidence hierarchy.
A journal article has no version of the prescribing information, so its version check does not apply. It is never marked out of date for that reason.
Three bands on a 0 to 100 score
- Fix
Below 60
One or more checks failed. The source needs work before the message is used again.
- Review
60 to 84
The source mostly holds up. A reviewer looks at the checks that were flagged.
- Solid
85 and above
The checks pass and the source is the right kind for the message.
All your messages in one view
Every checked message, grouped by band. Medical writers start with the messages marked fix.
Example of 52 messages, fictional medicine Varigel: solid 61%, review 27%, fix 12%.
How it runs
From your approved messages to a to-do list in four steps.
- 1
Bring your approved messages
Import your approved messages and their sources as your review system exports them, such as Veeva PromoMats or Aprimo. Or add a source yourself by dropping in a PDF or pasting a link.
- 2
Load the current prescribing information
The current version for the medicine and country, split into its numbered parts, so each source is read against the part it cites.
- 3
Check each message
Run the check from the message. The four checks return their results with the proof, and the message gets its score.
- 4
Work the list
Every checked message rolls up into one view. Medical writers start with the messages marked fix, and your reviewers decide on every change.
After a change
When the prescribing information changes, sources on the old version show up.
The version check looks up the current prescribing information each time it runs. In this example, version 8 lowers the dose for people with kidney problems from 20 mg to 15 mg. Messages that still cite version 7 are flagged, and their scores drop.
- Messages that cite the old version move to review or fix.
- Published studies have no version, so they keep their score.
- The overview shows how many messages need a new source.

What the Source check never does
- Change a message or a source. It flags each one with the proof.
- Approve a message. Your medical, legal and regulatory reviewers decide.
- Mark a published study out of date because it has no version.
- Train any AI model on your material.
Questions
Questions about the Source check.
- What is the Source check?
- A check on the source behind each approved key message. For each message, Juncture asks whether a source is cited, whether the cited part of the prescribing information supports the message, whether the numbers match the source, and whether the source is the current version. It weighs the kind of source and scores the message from 0 to 100.
- How does the version check work?
- Juncture looks up the current prescribing information live on the regulators' public websites: EMA and emc for Europe and the UK, DailyMed and openFDA for the US. A source recorded against an older version is flagged. A published study has no version of the prescribing information, so its version check does not apply.
- What do the score bands mean?
- Each message gets a score from 0 to 100 in one of three bands: solid at 85 and above, review from 60 to 84, and fix below 60. The overview groups every checked message by band, so medical writers can start with the weakest sources.
- Why does the kind of source matter?
- Some sources carry more weight than others. For a message the prescribing information can support, the prescribing information is the expected source and ranks above a journal article. Reviewers call this the evidence hierarchy. Juncture weighs it in every score.
- What happens to the score after the prescribing information changes?
- When the check runs after a new version is published, sources recorded against the old version are flagged and the scores of the messages that cite them drop. To follow a change across brochures, letters to doctors and AI answers as well, see the Change Check.
- Does it change our messages or sources?
- No. It flags each finding with the proof. Your medical writers make any change, and your medical, legal and regulatory reviewers approve it in your usual review process.
