Table 4. Correlation of ZFPM2 expression level with glioma grades.

Subtype	Grade a	n	Expression
			Range	Median	P b
Astrocytomas	II	8	3.29–146.50	62.97	0.006
	III	5	4.81–102.60	42.17
	IV	25	0.23–95.76	11.35
Oligodendroglial Tumors c	II	17	1.41–176.30	24.18	0.263
	III	14	6.92–83.95	21.39

^a Grade represents WHO classification of gliomas on the basis of histological features;

^b P values pertain to correlation between ZFPM2 expression and glioma grades. P value of less than 0.05 is highlighted;

^c Oligodendroglial tumors include the subtypes, oligodendrogliomas and oligoastrocytomas.
