Clinical characteristics of gastrointestinal immune-related adverse events of immune checkpoint inhibitors and their association with survival

Figure 3 Overall survival after initiation of immune checkpoint inhibitor treatment. Overall survival (OS) of patients with non-small cell lung cancer (NSCLC) and OS of patients with malignant melanoma (MM). A: In patients with NSCLC, there was no significant difference in OS among the three groups; B: The results were similar when stratified in stage III; C: The results were similar when stratified in stage IV; D: In patients with MM, there was a significant prolongation of OS in the immune checkpoint inhibitor (ICI) continuation group compared to the non-gastrointestinal immune-related adverse event (non-GI-irAE) group (P = 0.035); E: There was no significant difference in OS between the ICI continuation group and the non-GI-irAE group among patients with stage III disease; F: Among patients with stage IV disease, there was a significant prolongation of OS in the ICI continuation group compared to the non-GI-irAE group (P = 0.017). ICI continuation group: Patients who continued ICI treatment after developing GI-irAEs; ICI discontinuation group: Patients who discontinued ICI treatment after developing GI-irAEs; non-GI-irAE group: Patients with no GI-irAEs.
