Results for selected top interactions among top marginal loci with p-value less than 5×10⁻⁵ in Phase I studies.

<p>P_het is the heterogeneity p-value.</p

Forest plot for meta-analysis results of GxG between rs1571218 and rs10879357.

<p>Box sizes are proportional to the inverse variance for each study and the lines depict the confidence intervals. The diamonds represent the fixed effects meta-analysis results, with the width of the diamond representing the confidence interval. The results of two advanced adenoma studies (HPFS Adv Adnm and NHS Adv Adnm) are shown at the bottom but not incorporated in the meta-analysis.</p

Interaction pattern between rs10795668 and rs367615.

An illustration of different two-SNP interaction models. SNP 1 has genotype AA, Aa and aa; SNP 2 has genotype BB, Bb, and bb. A and B are the major alleles for SNP1 and 2, respectively.

<p>Each entry in the tables represents the risk of the corresponding genotype combination relative to the baseline (AA/BB). (a) Multiplicative interaction model; (b) Unrestricted interaction model; (c) Average Risk Due to Interaction (ARDI) model.</p

Regional interaction association plot for interacting region 5q21 with known CRC locus rs10795668.

<p>The left y-axis shows the -log10 of the meta-analysis interaction p value. The right y-axis shows the recombination rate. Each dot on the plot represents the result for one SNP. The diamond dot represents SNP rs367615 and the round dots represent other SNPs. Difference colors of SNPs indicate different LD strength between the corresponding SNP and rs367615, measured by r². The bottom of the figure shows the genes in the plotted region.</p
