OSCC patients with PNI had a higher incidence of lymph node metastasis. A OSCC patients with lymph node metastasis (LNM(+)) were classified based on the presence or absence of PNI. B OSCC patients with PNI classified based on the presence or absence of LNM. C The PNI status yielded an AUC value of 0.7012 to predict LNM in OSCC patients, which was better than that obtained for the T stage. Both the PNI status and T stage were included in the multivariant logistic regression model to yield the combination value
