Multivariate analysis: MRD values measured by RQ-PCR in BM as a single “punctual” time point

	TTP
Variables	HR	95% CI	P value
MIPI intermediate vs low	0.67	(0.27-1.70)	.4
MIPI high vs low	0.81	(0.27-2.41)	.7
Ki67 ≥30%	4.37	(1.74-11.0)	.002
PR after ASCT	4.18	(1.31-13.3)	.015
MRD POS at M6	7.80	(3.05-20.0)	<.001

M6, 6 months from transplant; MRD POS, positive minimal residual disease; PR, partial response.

84 randomized patients, landmark analysis starting from 6 months from transplant.
