From: Evaluation of extra capsular lymph node involvement in patients with extra-hepatic bile duct cancer
a, Kaplan-Meier (KM) survival curve of patients with lymph node metastasis (LNM). Patients were divided into two groups: those with and without extra-capsular lymph node involvement (ExCLNI). There was no significant difference between the two groups (p = 0.418). b, Kaplan-Meier (KM) survival curve of patients with LNM. Patients were divided into two groups according to location of the LNM (n1, n2, or n3). There was no significant difference between the groups (p = 0.213). LNM: Lymph node metastasis c, Kaplan-Meier (KM) survival curve of patients with and without ExCLNI. Patients were divided into three groups with ≥3 LNM, 2 LNM, or 1 LNM. There was no significant difference between these groups (p = 0.182). ExCLNI: Extra-capsular lymph node involvement; LNM: Lymph node metastasis.
