Kaplan–Meier survival analysis of patients with GC and risk score models. a A risk score model based on expression of five proteins. The patients were ranked according to their risk scores; the line divides the patients into low-risk and high-risk score groups. b Kaplan–Meier survival analysis of patients in the low-risk and high-risk score groups based on the five-protein risk score model. c Kaplan–Meier survival analysis of patients with different numbers of immunopositive proteins. d Kaplan–Meier survival analysis of patients in the low-risk and high-risk score groups based on TNM stage and vascular/lymphatic invasion. e Kaplan–Meier survival analysis of patients in the low-risk and high-risk score groups based on tumor size and age. p values were determined by log-rank testing
