TGFB2 and gastric adenocarcinoma: We found macrophage infiltration (P = .004) and TGFβ2 expression (P < .001) to significantly correlate with STAD prognosis (Figure 3C), whereas no significant correlation between prognosis and immune cell infiltration (P = .004) or TGFβ2 expression (P < .001) was observed in MESO (Figure 3D).
