Association of HCT with overall mortality, unadjusted, and adjusted models with HCT modeled as a time-dependent covariate

UnadjustedAdjusted 
HR (95% CI)PHR (95% CI)P
All patients (N = 692) 0.71 (0.57-0.88) .002 0.85 (0.66-1.09) .19 
Patients aged ≥65 y (n = 295) 0.65 (0.46-0.90) .01 0.79 (0.53-1.16) .22 
Patients with augmented HCT-CI scores ≥4 (n = 353) 0.63 (0.46-0.86) .0004 0.84 (0.58-1.21) .34 
Patients with ELN intermediate risk (n = 296) 0.55 (0.40-0.77) .0004 0.81 (0.55-1.17) .26 
Patients with ELN adverse risk (n = 248) 0.37 (0.25-0.54) <.0001 0.58 (0.38-0.89) .01 
Patients who achieved CR1 (n = 510) 0.85 (0.67-1.09) .20 0.96 (0.72-1.27) .75 
Patients who did not achieve CR1 (n = 182) 0.27 (0.15-0.51) <.0001 0.45 (0.22-0.90) .02

Adjusted for the augmented HCT-CI, age, ELN cytogenetic risk, relapsed/refractory AML at enrollment, posttreatment CR1 status, treatment intensity, sum PHQ-9, KPS, ADL, FACT-G, and 4-MWT (posttreatment CR1 status, sum PHQ-9, KPS, ADL, FACT-G, and 4-MWT modeled as time-dependent variables, with missing indicator to account for those without data).
