Forest plots of treatment-related adverse events leading to death. (A) The odds ratio of treatment-related adverse events leading to death calculated by the random effect (RE) model in Group A (PD-1/PD-L1 vs Chemotherapy). Subgroup analysis was performed based on tumor types. (B) The odds ratio of treatment-related adverse events leading to death calculated by the random effect (RE) model in Group B (PD-1/PD-L1 + Chemotherapy vs Chemotherapy). Subgroup analysis was performed based on tumor types. (C) The odds ratio of treatment-related adverse events leading to death calculated by the random effect (RE) model in Group C (PD-1/PD-L1 vs Placebo). (D) The odds ratio of treatment-related adverse events leading to death calculated by the random effect (RE) model in Group D (PD-1 vs PD-1 + CTLA-4). Subgroup analysis was performed based on tumor types. (E) The odds ratio of treatment-related adverse events leading to death calculated by the random effect (RE) model in Group E (PD-1 + CTLA-4 vs CTLA-4). (F) The odds ratio of treatment-related adverse events leading to death calculated by the random effect (RE) model in Group F (PD-1 vs CTLA-4). (G) The odds ratio of treatment-related adverse events leading to death calculated by the random effect (RE) model in Group G (PD-1/PD-L1 vs PD-1/PD-L1 + Chemotherapy).
