Nomogram-derived scores stratified patients into prognostically distinct subgroups with significant differences in OS and RFS.<h4>Conclusions</h4>This study established internally validated 3-year OS and RFS nomograms for pediatric <i>RUNX1::RUNX1T1</i>-positive AML with excellent discrimination and clinical utility. Here, RUNX1T1 is linked to acute myeloid leukemia.
