Relative distributions for PDAC diagnostic biomarkers. Levels of CA 19–9, haptoglobin (Hp), MMP-7, osteopontin (OPN), and TIMP-1 demonstrate considerable overlap in serum from healthy control subjects (CON), chronic pancreatitis patients (ChPT) and pancreatic ductal adenocarcinoma (PDAC) patients. Each data point represents the biomarker level for an individual sample. Note that serum CA 19–9 levels are presented using a logarithmic scale. Green horizontal lines indicate the 95% specificity threshold for the individual biomarkers.
