Model B (containing GATA3 expression) confirmed age (P = 0.006), GATA3 expression (P<0.001), depth of tumor infiltration (P<0.001), lymph node metastasis (P<0.001), and distant metastasis (P<0.001) as independent predictors of the overall survival of patients with gastric adenocarcinoma. Here, GATA3 is linked to gastric adenocarcinoma.
