a Kaplan–Meier survival curves showing the overall survival stratified by tumor response. (A) Uniform response; (B) dissociated response; (C) only stable lesions; (D) uniform progression. b Kaplan–Meier curves of overall survival (OS) after confirming progression stratified by different patterns of progression. (A) Dissociated response; (B) uniform progression. c Kaplan–Meier curves of overall survival (OS) stratified by continued PD-1 inhibitors in combination with RT or PD-1 inhibitor monotherapy after DR diagnosis. (A) PD-1 + RT/PD-1 therapy after DR diagnosis; (B) non-PD-1 + RT/PD-1 therapy after DR diagnosis
