Overall survival among all relapsed/refractory diffuse large B‐cell lymphoma patients (R/R DLBCL) (n = 736). (A) Stratified by age of at most 70 and older than 70 years at relapse. (B) Stratified by time to first relapse. (C) Stratified by secondary IPI score. * (D) Stratified by cell of origin. ** GCB, germinal centre B; IPI, international prognostic index. *, Based on age, stage, Eastern Cooperative Oncology Group performance status, lactate dehydrogenase level and number of extranodal sites at time of relapse/refractoriness. **, Information regarding cell of origin was based on immunohistochemistry mostly from primary diagnosis and categorized using the Hans algorithm
