IKZF1 and acute lymphoblastic leukemia: (58) conducted a meta-analysis of the correlation between IKZF1 deletion and survival; IKZF1 lesions could independently predict unfavorable OS (hazard ratio [HR] 1.60, 95% confidence interval [CI] 1.25–2.06) and event-free survival (EFS; HR 1.67, 95% CI: 1.28–2.17) in Ph− B-ALL.
