Error-bar plots of HDMI biomarkers for differentiation of invasive
breast cancer grade: (A) mircovessel fractal dimension (mvFD), (B) number of
branch points (NB), (C) number of vessel segments and (NV), (D) maximum diameter
(Dmax). * p < 0.05, ** p < 0.01, *** p <
0.001, **** p < 0.0001. HDMI = high-definition microvasculature
imaging.
