Unless otherwise indicated, numbers and percentages were only summarized among non-missing observations. –, p not calculated; ECOG, Eastern Cooperative Oncology Group; IPI, International Prognostic Index; LDH, lactate dehydrogenase; SD, standard deviation; ULN, upper limit of normal.
P < .05.
Prior HCT only included prior autoHCT because records with prior alloHCT were excluded.
The number of relapses was defined as the total number of lines before the index treatment where patient had a CR or partial response and relapsed later.
The IPI includes the following risk factors: age >60 years, elevated LDH, stage III or IV disease, ECOG performance status ≥2, and ≥2 extranodal sites.
