Boxplots summarize the median and IQR expression of five representative immune metagenes by race in the TCGA cohort. All tumor subtypes are included. Log2-transformed median values, available cases (n), Wilcoxon Rank Sum p-values, and Bonferroni adjusted p-values are displayed for each metagene. Colored points represent the log2-transformed, normalized expression of ER-positive, HER2-positive, and TNBC cases for each metagene.
