Fig. 3.

Relative diagnostic accuracy of proteins and CA19-9 as diagnostic biomarkers for PDAC vs healthy controls (A) and PDAC vs benign disease (B). Individual studies are presented as symbols, and head-to-head comparisons within studies are indicated with grey lines connecting two symbols. An rDOR lower than 1 indicates that the protein biomarker has a lower diagnostic accuracy than CA19-9. CrI, credible interval (derived from Bayesian hierarchical models); PDAC, pancreatic ductal adenocarcinoma.
