Table 1. nTBV values according to genetic alterations.

Genetic alteration	nTBV*	p-value†	KS test‡
EGFR expression(+) group (n = 22)
PTEN loss (n = 7)	10.3±8.1	0.046	Accepted(0.602)
PTEN no loss (n = 15)	5.6±2.3		Accepted(0.319)
MGMT methylation status (n = 25)
Methylation (+) (n = 16)	5.4±1.8	0.046	Accepted(0.845)
Methylation (−) (n = 9)	9.5±7.5		Accepted(0.594)

Note − Unless otherwise specified, the data are the means ± standard deviations.

^*nTBV: normalized relative tumor blood volume.

^†P-value for the comparison of means was calculated using unpaired Student’s t-test,

^‡KS test: Kolomogorov-Smirnov test for distribution normality.
