Receiver operator characteristic (ROC) analysis of serum IL-7 and G-CSF: a–c for differentiating patients with AIP from those with PDAC. a ROC curve for G-CSF. b ROC curve for IL-7, c ROC curve for combined index of G-CSF and IL-7. The respective areas under the curve (AUC) are 0.699 for G-CSF, 0.780 for IL-7, and 0.782 for the combination of both. d ROC curve for G-CSF for differentiating patients with AIP from those with CP (AUC = 0.804)
