Top log-likelihood test statistics for the large interaction effects. The blue solid curve shows the top 208 decreasingly ordered LLR test statistics, among which 160 values corresponds to SNP-pairs that exist on different chromosomes or have D' < 0.2, as represented by the green dot curve. The red dash curve shows the top 208 LLR test statistics for the interaction terms after a permutation of the disease status.
