Figure 2: The synthesized hazard ratios of OS according to ECOG performance status (≥2 vs <2) (based on multivariate results). (a) Forest plots. (b) Results of sensitivity analysis; the study on the left Y axis was excluded by turn. OS: overall survival; ECOG: Eastern Cooperative Oncology Group; HR: hazard ratio; CI: confidence interval; df: degree of freedom.
