Figure 2From: Nicotinamide N-Methyltransferase Upregulation Inversely Correlates with Lymph Node Metastasis in Oral Squamous Cell CarcinomaNNMT expression and clinicopathological parameters. The Mean-Whitney test was performed to evaluate any correlation between NNMT expression levels and stage (panel A), pT (panel B), and lymph node metastases (panel C). Panel D shows Kaplan-Meier survival curves of patients with OSCC (black square, patients bearing tumours with high NNMT expression levels; black diamond, patients bearing tumours with low NNMT expression levels).Back to article page
