Figure 1
IL-6 linkage disequilibrium (LD) plot. This plot was generated by using a Haploview program. Three SNPs form one block. The SNP name, e.g., SNP1, SNP2, and SNP3; indicates the three htSNPs genotyped in this study. Three common haplotypes (frequency ≥ 0.05) were identified. The level of pair wise r2, which indicates the association degree between two SNPs in LD block, is shown numerically in the cell of the LD structure. The level of pair-wise D', which indicates the strength of LD between two SNPs, is shown in the LD structure in gray scale.
