Cumulative incidence curves according to myeloma ISS stage (a) or ECOG performance status (b). The cumulative incidence of BSI is significantly higher in patients with either more advanced stage (p = 0.006) (Fig. 2a) or poor ECOG performance status (p < 0.001) (Fig. 2b). Note early deaths (within 90 days) were the competing events in the analysis
