PFS (A) and OS (B) for chemosensitive patients, stratified by sAAIPI risk group: low, intermediate, and high. (A) Kaplan-Meier curves of PFS and (B) OS in 108 chemosensitive patients with DLBCL, stratified by sAAIPI risk groups: low risk (0 factors), intermediate risk (1 factor), high risk (2-3 factors). sAAIPI risk factors comprise LDH greater than normal value, stage of III/IV, and KPS less than 80%.
