Depth of response by subgroup and treatment arm. The distribution of response pattern in subgroups based on number of prior lines, lenalidomide (LEN) or proteasome inhibitor (PI) treatment, IMiD refractoriness, and autologous stem cell transplant (ASCT). Bort bortezomib, CR complete response, IMiD immunomodulatory drug, NS not significant, PR partial response, sCR stringent complete response, VGPR very good partial response. Odds ratio and P value shown. *P < 0.05; **P < 0.01, ***P < 0.001
