NPM1 and acute myeloid leukemia: For the R/R AML cohort, in FLT3mut patients, adverse ELN risk was associated with an inferior response (odds ratio [OR], 0.2; 95% CI: 0.1–0.8; p = 0.025), whereas NPM1 co‐mutation was associated with a superior response (57.1%; OR, 6.7; 95% CI: 1.5–30.1; p = 0.014).
