	Continuous immunohistochemical variable
MRI parameter	CD34 MVD	αSMA PCI	CD105 MVD	CD61 MVD	Ki-67 (%)	Glut-1 (%)
K^trans per min	r²<−0.001	r²=−0.079	r²<−0.001	r²=−0.011	r²=−0.077	r²=0.018
	P=0.98	P=0.23	P=0.957	P=0.539	P=0.233	P=0.488
IAUGC₆₀ mM Gd per s	r²<−0.001	r²=−0.095	r²=−0.002	r²<−0.001	r²=−0.011	r²=0.036
	P=0.899	P=0.185	P=0.852	P=0.925	P=0.478	P=0.422

IAUGC=initial area under the gadolinium concentration-time curve; MVD=mean microvessel density; PCI=pericyte coverage index; SMA=smooth muscle actin.

The majority of calculations yield a negative regression line ie fall in MRI parameter following CA4P is greater if higher MVD.
