Forest plot of hazard ratios by PD-L1 expression comparing progression-free survival in patients who received IO-Chemotherapy vs Chemotherapy alone. Squares represent study-specific effect size (HR or RR). The area of square is inversely proportional to the standard error of the study and larger area indicates greater weight in the calculation of the pooled effect size. The horizontal line crossing the square represents the 95% CI. The diamonds represent the estimated overall effect, based on the meta-analysis. HR, hazard ratio; IO, Immuno-oncology; CI, confidence interval; PD-L1, programmed cell death 1 ligand 1
