Overall survival (OS) from the time of autologous stem cell transplant (ASCT). Group I represents patients who never received dialysis. Patients in group II received dialysis prior to ASCT. Group III started dialysis within 30 days of ASCT and group IV started dialysis after 30 days. Significant differences in OS were noted in group III (p = 0.003) and IV (p = 0.004) when compared to Group I.
