E2F2 and gastric cancer: E2F2 mRNA expression levels were significantly associated with favourable OS for all GC patients, HR = 0.56 (0.43–0.73), P=1.3 × 10−5 (Figure 2A), intestinal GC patients, HR = 0.49 (0.34–0.7), P=7.5 × 10−5 (Figure 2B), and diffuse GC patients, HR = 0.64 (0.45–0.91), P=0.012 (Figure 2C).
