Global Distribution of Total GWAS Sample Sizes by Country. This map illustrates the geographic distribution of cumulative participants in genome-wide association studies (GWAS) across various countries for years where data are available, highlighting global disparities in genetic research participation. Data were sourced from Mills, M.C., and Rahal, C. (2020) in their study "The GWAS Diversity Monitor Tracks Diversity by Disease in real-time," published in Nature Genetics, 52, pp. 242–243, https://doiorg.publicaciones.saludcastillayleon.es/10.1038/s41588-020-0580-y.
