Low-High grade progression heatmap: Heatmap of expression levels of the top markers for progression from DCIS to IDC in the low grade and high grade tumor subgroups. In each subtype, we use the upregulated genes which have good FDR under WV to stratify the samples. We show the 10 top genes for DCIS to IDC progression in LG and HG tumors. Since the sample sizes were small, the p values were computed using permutation tests and the FDR values were computed from these p values. The FDR values under WV for these genes are 0.6 for LG and 0.2 for HG.
