Stomatin-like protein 2 is overexpressed in epithelial ovarian cancer and predicts poor patient survival

Table 2 SLP-2 protein expression in the epithelial ovarian cancer group and the control groups

Group	Number of cases	SLP-2 expression (%)		χ ²	P value
Group	Number of cases	Low or no expression	High expression

2 Borderline ovarian tumour	20	11 (55)	9 (45)	15.300	<0.001^b
3 Benign ovarian tumour	20	14 (70)	6 (30)	12.764	<0.001
4 Normal ovarian epithelial tissues	20	20 (100)	0 (0)	41.303	<0.001
