Figure 1.

IL6 association results (−log₁₀ P) with stroke susceptibility and pairwise r² among genotyped SNPs in our population sample. The positions of the six SNPs relative to the IL6 gene (represented by an arrow) are indicated. The magnitude of linkage disequilibrium (r²) is represented by the white–black gradient shading and the values within each diamond. Association results above the line −log₁₀ P=1.3 are considered significant (P<0.050); and those above −log₁₀ P=2.1 survive Bonferroni correction (P<0.008). Linkage disequilibrium blocks were generated using the Gabriel et al (2002) method.
