Figure 2
A tumor marker panel consisting of CA19-9, OPN, and CHI3L1 predicts the presence of pancreatic cancer more accurately than CA19-9 alone. (A) Each row corresponds to 1 of 20 randomly assigned pancreatic cancer cases or healthy controls in the test set. Each column represents a tumor marker. Cells depict normalized log2 PLA units. (B) Rows are as A. Columns represent either a three-marker panel consisting of CA19-9, OPN, and CHI3L1, or CA19-9 alone. Cells depict the model-outputted probability that a given sample is either pancreatic cancer or healthy control, with a cutoff of p > 0.5 to be considered pancreatic cancer.
