The risk score for each gastric adenocarcinoma patient was calculated using the formula as described previously: Risk Score=H1 × X1 + H2 × X2 + ...+ Hp × Xp, where X1...Xp were the independent variables and H1...Hp were their hazard ratios, which were determined by multivariate Cox regression analysis. The gene discussed is HP; the disease is gastric adenocarcinoma.
