From: Elevated PD-L1 expression predicts poor survival outcomes in patients with cervical cancer
Meta-analysis of the association between PD-L1 and clinicopathological factors in cervical cancer: a lymph node metastasis (yes vs no), b tumor size (mm) (≥ 40 vs < 40), c FIGO stage (II vs I), d depth of invasion (mm) (≥ 10 vs < 10), e lymph-vascular invasion (yes vs no), f age (y) (≥ 45 vs < 45)
