Pearson correlation between RNF169 and USP7 expression in breast cancer

Parameters	RNF169 expression	USP7 expression
RNF169 expression
Pearson correlation	1	0.216*
Sig. (two-tailed)		0.034
N	108	96
USP7 expression
Pearson correlation	0.216*	1
Sig. (two-tailed)	0.034
N	96	104

The nuclear expression of USP7 and RNF169 was scored semiquantitatively according to their intensity and percentage of stained tumor cells. The median values were used as a cutoff between high and low nuclear expression. The Pearson correlation between RNF169 and USP7 nuclear expression showing significant (Sig.) positive correlation is P = 0.034.

^*Correlation is significant at the 0.05 level (two-tailed).
