  1. MRD minimal residual disease, D-Rd daratumumab plus lenalidomide/dexamethasone, Rd lenalidomide/dexamethasone, ORR overall response rate, CR complete response, sCR stringent complete response, VGPR very good partial response, PR partial response, SD stable disease, PD progressive disease, NE not evaluable.
  2. aP value was calculated using the Cochran–Mantel–Haenszel chi-square test.
  3. bP value was calculated using the Fisher’s exact test.
