The data source and statistical methods for GBD 2019 have been described elsewhere12,13. Briefly, the GBD estimated data for 369 diseases and injuries and 84 risk factors at global, regional, and national levels from 1990 to 2019. We extracted data from the Global Health Data Exchange (GHDx) website (http://ghdx.healthdata.org/gbd-results-tool). We used the term “stomach cancer” as the “cause”; we used the terms “incidence” and “death” as the “measure”.

Gastric cancer included all diagnoses coded according to the International Classification of Disease 10th Revision, ICD-10 as C16–C16.9, Z12.0, and Z85.02–Z85.02812. Data on the age-standardized incidence rate (ASIR) and age-standardized death rate (ASDR) at global and national levels were extracted from GBD 201914. The geographic locations included Mongolia, China, the Republic of Korea, Japan, and DPRK. Estimates were reported with 95% uncertainty intervals (UIs).
