Fig. 1. Kaplan–Meier curve comparing overall survival of patients whose tumors did or did not harbor PBRM1 mutations.
a The OS of the PBRM1-mutant patients was worse than that of those without the mutation in the cohort of ICB-treated patients. b There is marginally significant difference in OS between the PBRM1 mutation subgroup and the PBRM1 wild type subgroup in the cohort of non-ICB-treated patients. No survival difference between PBRM1 mutation types (LOF mutation and non-LOF mutation) were observed in the cohort of ICB-treated (c) and non-ICB-treated (d) patients. OS overall survival, ICB immune checkpoint blockade, LOF loss of function.
