Figure 2: Density distribution of β values across samples.

(a) The distribution of raw β values for all three BM subtypes before normalization. (b) The distribution of β values after normalization for all three BM subtypes. BM subtype is indicated by the color of the line, with green lines representing breast cancer brain metastases (BCBM), orange lines representing lung cancer brain metastases (LCBM), and purple lines representing melanoma brain metastases (MBM).
