Multifactor dimensionality reduction (MDR) analysis of interaction between the candidate SNPs of CYP4A22 (rs76011927, rs12564525, rs2056900, and rs4926581). (A) SNP-SNP Interaction Dendrogram: the color represents the degree of redundancy or synergy between SNP-SNP; the closer the color is to red, the more synergy, and the closer to blue, the more redundancy. (B) Fruchterman-Reingold: values in nodes represent the IGs of individual attribute (main effects). Values between nodes are IGs of each pair of attributes (interaction effects)
