Heatmap showing how significantly the effect alleles are enriched or depleted in each population for the 225 obesity risk SNPs. Each row represents an SNP, and each column represents a population. The color bar above the heatmap shows continental group each population belongs to. Keys for populations can be found in Table 1. A cell in the heatmap is color coded according to the log10 of P-value, which tests the enrichment/depletion of an effect allele in a population in comparing with the overall average. If an effect allele is enriched, the cell is colored red based on the negative value of log10P, whereas if an effect allele is depleted, the cell is colored green based on the value of log10P
