P values (cases vs comparators): education, P = .061; Charlson Comorbidity Index (CCI), P = <.001.
∗
Cutoff in landmark analysis is 12 months; patients with a HD-ASCT thereafter will remain unexposed in the analysis.
†
Fifty-five patients with MCL have a follow-up shorter than 12 months and do not contribute to the analysis.
‡
Patients are matched on birth year, not exact age; therefore, the coherence is not perfect.
