(a) Publication bias on the differences of serum endostatin levels in different stage of TNM in gastric cancer. (b) Publication bias on the differences of serum endostatin levels in the LN invasion-positive and LN invasion-negative gastric cancer. (c) Publication bias on the differences of serum endostatin levels between patients with poorly differentiated and well-differentiated gastric cancer. (d) Publication bias on the differences of serum endostatin levels between intestinal- and diffuse-type gastric cancers.
