Figure 5

Tissue composition of pre-chemo biopsies collected with (n=139) and without (n=33) ultrasound, post-chemo biopsies collected with ultrasound (n=56) and of tissue fragments collected at the time of surgery (n=64). Pre-chemotherapy biopsies collected with ultrasound are statistically different from those collected by the surgeon (with no ultrasound). Pearson's χ2-test P-value=7.492e−06.
