Figure 4.

Variable and marker boxplots by WGCNA* mortality group. Kruskal-Wallis p-values are reported for the comparison of each variable and marker to the WGCNA* patient groups, where the WGCNA* patient groups are color coded to indicate low (white), moderate (grey) and high (black) mortality. A. Metastasis, stage, ER+ and death are significantly related to the WGCNA* groups (p < 0.05). B. The top 10 markers related to survival that achieved significance at p < 0.05 in a univariate Cox proportional-hazards model when dichotomized at an optimal cut-point. The boxplots indicate that no variable or marker by itself can define the WGCNA* groups. Abbreviations are as follows, "LNI" stands for Lymph Node Involvement, "cyt" indicates the TMA marker was expressed in the cytoplasm and "nuc" indicates nuclear expression.
