Fig. 1From: Combined PD-1/PD-L1 and tumor-infiltrating immune cells redefined a unique molecular subtype of high-grade serous ovarian carcinomaPrognostic significance of PD-1/PD-L1 in HGSOC. Kaplan-Meier analysis for overall survival of patients with higher (red) or lower (blue) PD-1/PD-L1 expression in the GSE53963 (A), GSE32062 (B), GSE135820 (C), and TCGA (D) databases. The log-rank test was used to compare groups, and p < 0.05 was considered significant.
