The Kaplan-Meier survival curves for metastatic or recurrent gastric carcinoma patients with different scores. The log-rank test method with pairwise comparisons was used to compare survival times among the different risk subgroups. Total scores were calculated according to the prognostic nomogram. Cut-off values of 100 and 200 were used to divide patients in the AHMU cohort (A) and the MMH cohort (B); Patients in the AHMU cohort (C) and the MMH cohort (D) were divided into three groups according to the simplified score of 0 ~ 1, 2 ~ 4, and 5~.
