We extracted previously reported GWAS association within 500 kb of and r2 > 0.7 with any BMI-index SNP from the NHGRI GWAS catalogue71 (http://www.genome.gov/gwastudies; Supplementary Table 17a, b). For studies reporting greater than 30 significant hits, additional SNP-trait associations were pulled from the literature and compared to BMI index SNPs the same as with other GWAS catalogue studies.
