Associated CNAs. A Monte Carlo simulation was performed to determine whether pairs of CNAs were positively or negatively associated. rCNA pairs on the same chromosome were not analyzed and are marked in gray. Significantly associated pairs of CNAs (P ≤ .05) are denoted in shades of green (positive association) or red (negative association). The lower left of a box represents FL cases and the upper right represents tFL cases. The results are ordered according to a hierarchical cluster tree generated using Cluster 3.0.
