ROC curve analysis of PET accuracy in identifying lymph node metastases with different levels of macrophage infiltration.
(A) ROC curve for PET accuracy in patients with high macrophage (CD163+ cells) infiltration. The AUC value is 0.784. (B) ROC curve for PET accuracy in patients with low macrophage (CD163+ cells) infiltration. The AUC value is 0.737.
