To assess the role of bortezomib-based maintenance therapy specifically in patients after ASCT, we excluded the trial involving transplant-ineligible patients 24 and performed the meta-analysis again, which showed improved OS (HR = 0.72, 95% CI 0.54–0.96, P = 0.025) and a clear trend toward improved PFS (HR = 0.84, 95% CI 0.699–1.001, P = 0.052).
