A shows the results using non-HLA lead variants and B shows the results after including one lead variant in LD with HLA-DQB1*06:02. The x and y axes show the effect sizes (log odds ratio) of each SNP for both phenotypes. The horizontal and the vertical lines demonstrate the standard errors of the effect sizes.
