PSIP1 and ovarian epithelial tumor: However, analysis of 1171 epithelial ovarian tumors in KM-plotter [22], the online tool for survival-associated biomarkers, showed a strong association between high PSIP1 expression and shorter PFS (Figure 6; HR = 1.44 (95% CI 1.23 - 1.68; P = 6.6 × 10−6 for comparison above and below median PSIP1 expression).
