SNHG5 and metastatic malignant neoplasm in the lymph nodes: The results of the subgroup analysis revealed a noteworthy correlation between SNHG5 expression and easier-to-lymph node metastasis in the subgroup of patients with a nondigestive system invasion (OR = 1.992, 95% CI 1.204–3.295) and a nonsignificant correlation in the subgroup of patients with a digestive system invasion (OR = 0.467, 95% CI 0.175–1.245) (Table 4).
