Inverted Kaplan-Meier plot of incident GC in the CKB and Changzhou cohorts by GCRS. Participants in the a CKB and b Changzhou cohorts were divided into low (bottom 20% of the GCRS: ≤ 13.6), intermediate (20–80%: 13.7~30.6), and high (top 20%: ≥ 30.7) risk groups. The cumulative incidence of GC was calculated by using the Kaplan-Meier method. The risk table under the plot showed the number at risk and the corresponding cumulative number of incident GC cases at years of follow-up. GCRS, gastric cancer risk score; CKB, China Kadoorie Biobank
