Subgroup analysis of overall survival
(A) Forest plot of overall survival in the intention-to-treat population. (B) Kaplan-Meier plot of overall survival in transplantation-eligible patients. (C) Kaplan-Meier plot of overall survival in transplantation-ineligible patients. CR=complete response. CRD=cyclophosphamide, lenalidomide, and dexamethasone. CTD=cyclophosphamide, thalidomide, and dexamethasone. CVD=cyclophosphamide, bortezomib and dexamethasone. HR=hazard ratio. KCRD=carfilzomib, cyclophosphamide, lenalidomide, and dexamethasone. MR=minimal response. NC=no change. PD=progressive disease. PR=partial response. VGPR=very good partial response. *Likelihood ratio test for heterogeneity of effect amongst patients with subgroup data available.
