Univariate outcome data in dependency of the numeric accumulation of the 7 most recurrent deletions (IKZF1, PAX5, CDKN2A/2B, BTG1, EBF1, ETV6, and RB1). (A) Proportionate distribution of the number concomitant recurrent deletions over all samples, (B) outcome of DFS in dependency of the number of the above described deletions, (C-E) outcome data in dependency of the presence of 0 or 1 deletion vs 2 or more, (C) OS, (D) DFS, (E) REM, and (F) leukocyte count in dependency of the number of deletions.
