Figure 2. Kaplan–Meier plots of the association of PA1 expression in the nucleus with RFS; A and BCSS; B in the entire cohort.

When PA1 protein expression was defined as either positive or negative, positive cases seemed to have a longer survival than negative ones in Kaplan–Meier method analysis (RFS, P = 0.023), but no slightly correlation with BCSS (P = 0.23). No association could be found between PA1 protein expression in the cytoplasm and RFS, BCSS (data not shown). Abbreviations: RFS, relapse-free survival; BCSS, breast cancer-specific survival.
