marginally significantp -value = 0.050
In the Cox regression analysis, the occurrence of metastasis had a marginally significant association with tumor thickness (B = 0.227, 95-CI: 0.111 to 0.343, p -value = 0.050), and there was no significant association between recurrence of the tumor ( p -value = 0.662) or TNM staging ( p -value = 0.32) and the incidence of metastasis.
