Kaplan–Meier survival analysis concerning KLK7 mRNA expression as well as KLK5 + KLK7 mRNA expression in advanced HGSOC. a Patients with elevated KLK7 mRNA expression levels have a significantly worse PFS (p = 0.021), compared to those with low mRNA expression levels. b The combined factor KLK5 + KLK7 mRNA also represents a prognostic factor for PFS (p = 0.011). Both factors show a trend towards significance for OS
