HP and gastric cancer: Multivariate Cox analysis showed that age (HR = 1.849, 95% CI = 1.230–2.779, P = 0.003), Hp (HR = 1.639, 95% CI = 1.081–2.484, P = 0.020), and the hypoxia-related lncRNA signature (HR = 2.364, 95% CI = 1.518–3.682, P < 0.001) were independent risk factors for predicting OS in gastric cancer (Figure 6B).
