Figure 1
Plasma levels of 21 tumor markers in pancreatic cancer patients and healthy controls measured by proximity ligation assay. Each boxplot corresponds to a single tumor marker measured in 95 samples by proximity ligation assay. Pancreatic cancer cases (52) are depicted at left, healthy controls (43) at right. Y-axis corresponds to log2 PLA units. Central bars show the median for each cohort, boxes represent the interquartile 50th percentile (IQ50). Whiskers represent 1.5 times the IQ50.
