However, the pooled results indicated that high lncRNA BCAR4 expression was associated with lymph node metastasis (OR 3.68, 95% CI: 2.25–6.00; P < .001, I2 = 27%), high tumor stage (OR 3.19, 95% CI: 1.98–5.13; P < .001, I2 = 0%), and distant metastasis (OR 3.83, 95% CI: 2.15–6.82; P < .001, I2 = 0%). Here, BCAR4 is linked to metastatic malignant neoplasm in the lymph nodes.
