Figure 9. Survival plots. All patients were divided into two groups based on the expression level of STAT1: a high expression group and a low expression group. Data were extracted from a microarray (Affymetrix ID: 200887_s_at). The hazard ratio (HR) with 95% confidence intervals (in parentheses) and log-rank P for OS, PFS, and PPF were calculated, respectively. (A) Kaplan-Meier curves of the OS, PFS, and PPS of all patients with OC are presented. (B) Kaplan-Meier curves of the OS, PFS, and PPS of PTX-treated patients with OC are presented. Number, case number; OV, ovarian cancer; low, low expression of STAT1; high, high expression of STAT1; PTX, paclitaxel; STAT1, signal transducer and activator of transcription-1.
