CIR for IKZF1 status among subtypes of ALL. CIR with death as a competing event was calculated for the DCOG ALL-10 study cases with (A) high hyperdiploid ALL (>50 chromosomes) including 21 IKZF1-deleted and 87 wild-type cases; (B) ETV6-RUNX1–positive ALL including 4 IKZF1-deleted and 100 wild-type cases; (C) non–BCR-ABL1-like B-other ALL including 5 IKZF1-deleted and 22 wild-type cases; and (D) BCR-ABL1-like ALL including 10 IKZF1-deleted and 19 wild-type cases. For each feature, the CIR at 5 years of follow-up is indicated in parentheses.
