Association of DOX-induced cardiotoxicity with CBR3 V244M genotype status We compared left ventricular systolic function from pre- and post-DOX treatment echocardiograms in each CBR3 V244M genotype group and found a highly significant effect of DOX treatment on left ventricular systolic function (F[1,89] = 50.33, p < 0.0001, two-way ANOVA).
