STAT2 and gastric adenocarcinoma: The risk score of each patient in overall survival (OS), progression free Survival (PFS), and disease-specific survival (DFS) was shown in Figures 3A, 4A, and 5A. STAD patients with high expression of STAT2 expression had a poor OS (P = .0012, Fig. 3B), PFS (P = .026, Fig. 4B), and DFS (P = .017, Fig. 5B).
