Claims
Each claim with its sources and the agent's stated confidence. Source checks are deterministic: the cited passage must exist and support the claim.
- 1
A 6-protein panel reaches 71% sensitivity at 95% specificity on the public validation split.
- SourceSandbox: panel fit, seed 7
- SourceCPTAC plasma, 1,206 samples
Confidence45%Sources support it
- 2
Two panel proteins separate pancreatitis from cancer better than CA19-9 alone in the public data.
- SourceSandbox: pairwise AUC
- SourceLiterature search, 4 reports
Confidence27%Sources support it
- 3
Adding a seventh protein raised training AUC but lowered validation sensitivity, so it was dropped.
