Extended Data Fig. 4: Characterizing the basal/intermediate signature.

a, Comparison of BCR-free rate between the high and low groups stratified using Basal/Intermediate signature in the indicated datasets. P-values are calculated using Cox proportional hazard model (CoxPH) and not adjusted for multiple comparisons. Numbers in brackets show 95% confidence interval (CI) for hazard ratio (HR). b, Correlation between tumour purity corrected CCL2 expression and basal/intermediate signature in TCGA. c, Correlation between macrophage, T cell and basal/intermediate signature across multiple datasets. Two-sided P values calculated for Spearman’s rank correlation and not adjusted for multiple comparisons.
