Probability of recurrence of molecular clonality assessed by IgH-CDR3 consensus PCR and gene scanning after autologous SCT according to mutational status.

The proportion of recurrence of molecular recurrence of the unmutated group (dotted line, median event-free survival 25 months) versus the unmutated group (solid line, median event-free survival not reached) by Kaplan Meier estimation (P = .0006; HR, 4.8; 95% CI, 1.9-11.1).
