Bubble plot with a fitted meta-regression line of the log hazard ratio for a, e publication year, b, f sample size, c, g region of research, and d, h positive rate of PD-L1 (%). ad Represent overall survival; eh represent recurrence-free survival. The size of circles is proportional to the weight of each study in the fitted random-effects meta-regression. PD-L1 programmed death ligand 1, HCC hepatocellular carcinoma
