European ancestry sample is plotted towards the left in white and non-European ancestry is plotted towards the right highlighted in different colors. Plotted is the number of cases included in each published AF GWAS study or meta-analysis. 10 out of 12 studies include predominantly European ancestry samples, shown in white. Two studies are Japanese only and Korean only. Within the multi-ancestry meta-analyses Roselli et al.[28] included the largest proportion of non-European cases including Japanese, Brazilian, African American and Hispanic samples.
