Dash (—) indicates lack of statistical significance in the multivariate model. Variables considered in the multivariate analysis included: age (years), white blood cells (× 109/L), platelets (× 109/L), bone marrow blast percentage, therapy-related AML vs non–therapy-related AML, secondary AML vs nonsecondary AML, cytogenetics (diploid vs nondiploid), n of TP53 mutations (>1 vs 1), TP53mut VAF, TP53 loss by cytogenetics, and transplantation (time dependent).
