Kaplan-Meier curves for OS. (A) OS in CN-AML patients according to IDH2 mutations. Dotted line represents patients with mutated IDH2 (n = 33); and solid line, patients with unmutated IDH2 (n = 239; log-rank test, P = .792). (B) RFS in CN-AML patients according to IDH2 mutations. Dotted line represents patients with mutated IDH2 (n = 27); and solid line, patients with unmutated IDH2 (n = 182) (log-rank test, P = .524).
