Up-regulation of cell cycle arrest protein BTG2 correlates with increased overall survival in breast cancer, as detected by immunohistochemistry using tissue microarray

Table 3 Difference in protein expression between tumours from 5-year overall survivors and tumours from deceased patients

	Dead patients		Alive patients
Protein	Protein expression positive (%)	Protein expression negative (%)	Protein expression positive (%)	Protein expression negative (%)	not available (No of samples)	P-value dead vs. alive patients

P-values were calculated using a two-tailed Fisher's exact test. The samples designated as not available had few tumour cells, large tissue loss or affluence of necrotic tissue.
