Figure 1. Interaction dendrogram for the six polymorphisms modeled by MDR. The colors comprise a spectrum representing a continuum from synergy to redundancy. The red color represents a high degree of synergy (positive information gain), orange a lesser degree, and gold represents the midway point between synergy and redundancy. On the redundancy end of the spectrum (not appeared in our model), the highest degree is represented by the blue color with a lesser degree represented by green.
