Association of BV-TMEM and LV-TMEM with breast cancer subtypes in a patient cohort.

	# Of Cases	# Of Cases with BV-TMEM (%)	# Of Cases with LV- TMEM (%)	Chi-Square
Luminal	42	42 (100%)	0 (0%)	p > 0.05
HER2+	9	9 (100%)	1 (9%)
TNBC	9	9 (100%)	1 (9%)

Fisher’s exact test was used instead of Chi-Square, if expected value in any cell was <5. Abbreviations: #, number; BV, blood vessel; LV, lymphatic vessel; TMEM, tumor microenvironment of metastasis; Luminal, luminal breast cancer; HER2, human epidermal growth factor receptor 2-enriched breast cancer; TNBC, triple-negative breast cancer.
