Figure 3

Forest plots of tumour cell PD-L1 expression for predicting (a) OS, (b) CSS, and (c) DFS for patients with organ-confined tumours after cystectomy. PD-L1: programmed death-ligand 1; +/-: positive/negative; OS: overall survival; CSS: cancer-specific survival; DFS: disease-free survival; CI: confidence interval; IV: inverse variance; SE: standard error.
