1-MM	228	Reference
2-MM	371	0.9 (0.6-1.4)	.662
3-MM	32	1.5 (0.6-3.8)	.411
Patients who engrafted
0-MM	47	0.7 (0.4-1.4)	.350
1-MM	254	Reference
2-MM	418	1.0 (0.7-1.4)	.804

MM indicates mismatch; and RR, relative risk.

^*Other predictive variables, such as advanced disease, diagnosis of JCML, and younger age (< 10 years), were associated with an increased risk of relapse. TNC, transplant center experience, year of transplant, and patient ethnicity were not predictive of relapse.

^†The subanalyses of those transplanted in relapse or remission excludes those with unknown disease status at time of transplantation and MDS.
