Variable	TTP to MM
	Univariable		Multivariable∗
	Hazard ratio	P value	Hazard ratio	P value
Minimal marrow involvement	1.81 (1.10-2.99)	.020	0.72 (0.23-2.22)	.570
Abnormal sFLC ratio	2.26 (1.16-4.39)	.011	1.48 (0.63-3.52)	.370
Presence of HR FISH cytogenetics	3.23 (1.66-6.27)	.0006	5.88 (2.47-14.0)	<.001

The boldface P values are statistically significant at P < .05.

^∗Multivariate model included 49 patients with 31 events.
