Abbreviations: CI, confidence interval that was calculated using allele 1 as the reference; Chr, chromosome; GWAS, genome-wide association study; maf, minor allele frequency; OR, odds ratio that was calculated using allele 1 as the reference; SNP, single-nucleotide polymorphism.
The P-values of the GWAS were the genomic-control P-values (PGC). The combined P-values were calculated by the inverse variance method. The P-values of heterogeneities (Phet) across the population were estimated formally using the Breslow–Day test. Chromosome location was based on hg18 (Genome Build 36.3).
