(A, B) PFS and OS curves in patients with OCCC. (C) Patients with PD-L1^low (yellow solid line) presented a better survival outcome than those with PD-L1^high (blue dotted line). (D) Patients with PD-L1^high (blue dotted line) showed significantly worse PFS compared with those with low expression (yellow solid line).

OCCC, ovarian clear cell carcinoma; OS, overall survival; PD-L1, programmed death-ligand 1; PD-L1^high, high PD-L1 expression; PD-L1^low, low PD-L1 expression; PFS, progression-free survival.
