Table 1:

Significance of mean MK′, nMK′, MD, and nMD values in different tumor grades^{^a}

Tumor Type	MK′	nMK′	MD	nMD
HGG/LGG	.028^{^b}	.058	.383	.511
GBM/all	<.001^{^b}	.002^{^b}	.006^{^b}	.006^{^b}
GBM/HGG	.003^{^b}	.011^{^b}	.004^{^b}	.004^{^b}
AC3/all	.135	.135	.063	.033^{^b}
AC3/HGG	.011^{^b}	.031^{^b}	.024^{^b}	.019^{^b}

Note:—AC3 indicates grade III astrocytoma.
↵a Mean MK′, nMK′, MD, and nMD values in the tumor core were compared between different tumor grades, and the resulting P values are listed.
↵b A P value of <.05 indicates a significant difference between groups.
