Claim

In the testing cohort, PANXEON combined with CA19-9 detected stage I–II pancreatic ductal adenocarcinoma with 86.8% sensitivity, with false-positive rates of 3.2% in low-risk controls and 15.6% in high-risk controls.

Assessment

Supported

Score: 0.9908 under ledger-default@0.3.0 at snapshot 27745

2 of 4 review checks done · 1 counted · 1 by the author only

Main unresolved issue: 4 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:78de54be-827c-8f56-8c80-fecdff28a421

Not yet independently audited.Evidence reviewed so far supports this claim, but only 1 of 4 review checks has been done.Every quoted passage was confirmed on the page when Galedra fetched it.

Related: NARROWS incoming: Supported

Why?

Strongest counted support: The passage directly reports 86.8% sensitivity and the 3.2% and 15.6% false-positive rates for the testing cohort. weight 1.800000 evidence

Suppressed as dependent: The primary paper reports 86.8% sensitivity for stage I–II PDAC and false-positive rates of 3.2% and 15.6% in the stated control groups.; Cancer Network independently reports the same testing-cohort performance figures for the PANXEON composite.

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Supported.

How the number was reached

Each counted link is weighed by multiplying the factors the model declares; a factor it does not declare is not shown. Every factor name below links to what that number means.

prior 0.50 → log-odds 0.000000 + 4.680000 (the counted weights) = 4.680000 → probability 0.9908

Under neighbouring settings of the same model: 0.9636 to 0.9977, a spread of 0.0341.

Half-even rounding, six places for weights and four for the probability. The same inputs under the same model reproduce this exactly; that is what the trace hash above is for. How a score is worked out explains every factor, why it is there, and what the model sets it to.

Evidence against

None.

Qualifications

The source explicitly labels the figures as testing-cohort results and separates low-risk from high-risk controls.

From Liquid biopsy for early detection of pancreatic ductal adenocarcinoma Read 2026-09-28 Relevance DIRECT Steps 0 Counted

The sampling and control-group scope materially limits generalization beyond the reported cohort.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.
