Figure 2From: Identification of potential serum peptide biomarkers of biliary tract cancer using MALDI MS profiling Peaks discriminatory for BTC versus benign biliary disease and healthy controls. Box-and-whisker plots of peak area (5–95 percentile) are shown for differential peptide peaks for biliary tract cancer BTC; dark grey), benign disease (B; light grey) and healthy control (HC; white) samples.Back to article page
