Supplementary Figure 1

Quantile–quantile plot of the observed –log10 (P values) versus the expectation under the null hypothesis. Data are presented for the meta-analysis of cohorts 1 and 2 after imputation and quality control. The overall genomic control inflation factor (λGC) is 1.023, indicating that inflation due to population structure is negligible. SNPs at which the P value is smaller than 1 × 10–8 are represented by triangles at the top of the plot. The gray region represents the 95% concentration band.
