The Prognostic Value of Lymph Nodes Dissection Number on Survival of Patients with Lymph Node-Negative Gastric Cancer

Table 3

Prognostic factors retained in multivariate analysis.

Factors	𝑃 value	Relative risk	95% CI
Invasion depth	<0.001	1.704	1.418–2.048
No. of examined lymph nodes	<0.001	1.616	1.468–1.779

Cox proportional hazard analysis was used to investigate the potential prognostic factors of survival in GC patients without lymph node metastasis.
