HCMBL and CLL stratified by both TML and CLL-IPI for association with TTFT. Cumulative incidence plot of progression to first treatment among individuals with HCMBL and CLL stratified by TML (any vs no mutations) and CLL-IPI (low risk vs more than low risk). TML is the number of genes out of 59 with high-impact mutations (excluding TP53). CIF Est, cumulative incidence function estimation.
