The relationship between SPAG5 expression level and clinic characteristics in glioma patients.

		SPAG5 expression level		Total	P value
		Low	High
Age	≤46	212	128	340	<0.001
	>46	122	205	327
Total		334	333	667
Sex	Male	188	196	384	0.502
	Female	146	137	283
Total		334	333	667
Grade	LGG	317	198	515	<0.001
	GBM	17	135	152
Total		334	333	667

According to the median of the SPAG5 mRNA expression, the 667 glioma specimens were further divided into low SPAG5 expression group (n = 334) and high SPAG5 expression group (n = 333). LGG, low-grade glioma; GBM, glioblastoma; SPAG5, sperm-associated antigen 5.
