Values in boldface indicate statistical significance. ACA type was excluded from multivariable analyses, as the specific ACAs and the ACA type variables are related. 9p22/KMT2A::MLLT3 refers to t(9;11)(p22;q23), 10p12/KMT2A::MLLT10 to t(10;11)(p12;q23), 6q27/KMT2A::AFDN to t(6;11)(q27;q23), 19p13 to t(11;19)(q23;p13) without ascertained subband, 19p13.1/KMT2A::ELL to t(11;19)(q23;p13.1), 19p13.3/KMT2A::MLLT1 to t(11;19)(q23;p13.3), 1q21/KMT2A::MLLT11 to t(1;11)(q21;q23), 10p11.2/KMT2A::ABI1 to t(10;11)(p11.2;q23), Xq24/KMT2A::SEPT6 to t(X;11)(q24;q23), 17q21 to t(11;17)(q23;q21), 4q21/KMT2A::AFF1 to t(4;11)(q21;q23), 1p32/KMT2A::EPS15 to t(1;11)(p32;q23), and 17q12 to t(11;17)(q23;q12).
NA, not applied (not significant variables in univariable Cox regression analyses, see supplemental Table 5); abbreviations are explained in Table 1.
Omitted from the final multivariable model of EFS/CIR/OS because of a P-value > .10 in stepwise backward elimination.
