Fig. 1: Number of breast cancer samples in TCGA by definition, race, and PAM50 subtypes.

Pie charts depicting the number of breast cancer samples in TCGA PAM50 subtypes: Basal, Her2, LumB, LumA, Normal-like for all samples (a), for samples from AA patients (b), or for samples from W patients (c). d Scores of the expression level of XIAP, OSR-, Immune-, and TGFβ-related gene signatures in breast cancer subtypes. Box plots overlaid with scatter plots depicting the calculated score for XIAP-, OSR-, immune-, and TGFβ-related ASR gene signatures in the indicated breast cancer subtypes and stratified by patient race, AA or W. The Wilcoxon signed-rank test was used to examine significance (*adjusted p-value < 0.05; **adjusted p-value < 0.001; ***adjusted p-value < 0.0001; and ns, not significant). The center line represent the medians and the bounds of box represent the confidence intervals.
