In total, 37 significant results (p<0.05) were identified in the Cox regression analysis using the cellular proportions predicted by HIDE, including 5 in patients with the triple negative breast cancer subtype, 10 in HER2-positive breast cancer, 6 in luminal A, 8 in luminal B, and 8 in cases where breast cancer subtypes were not differentiated. Here, ERBB2 is linked to triple-negative breast carcinoma.
