Multivariate proportional hazards analysis

		Event-free survival			Survival
	%*	HR	P	HR	P
PR, MS, and MF versus other	37	2.41	< .001	1.98	.004
Any cytogenetic abnormalities	38	1.60	.014	1.98	.005
β2-microglobulin level of 339 nM or higher	44	1.47	.061	1.55	.092
LDH level of 190 μ/L or higher	34	169	.011	1.94	.009

n = 255 (of 256 patients); 1 patient is missing cytogenetics. There were 115 progression events and 74 deaths. The following variables were not significant: (1) with the sample of 255, age of 65 years or older was not significant in either analysis (P = .07 for EFS); (2) C-reactive protein level of 4 or higher; and (3) albumin level of 3.5 g/dL or less.

^*This column refers to the percentage of 255 cases having the incidence of each clinic feature specified in the first column of each row.
