Comparison of high- and low-intensity bridging strategies. (A) Overall survival from start of bridging stratified by bridging treatment intensity for entire cohort (A, left, p=0.1 by log-rank) or only patients with morphologic disease (bone marrow blasts > 5% or EMD) (B, right, p=0.8 by log-rank). (C) Rates of grade 3–4 infectious toxicity during the bridging period for all patients with available data (n=81). Y-axis reported as frequency of total population, with labels showing total number of patients.
