ALB and acute myeloid leukemia: The results suggested that diagnosis (AA vs. AML, HR: 4.373, 95% CI 1.169–16.359, P = 0.028), disease status before transplantation [partial remission (PR)/nonremission (NR) vs. CR, HR: 3.610, 95% CI 1.283–10.157, P = 0.015), conditioning regimen (RIC vs. MAC, HR: 3.971, 95% CI 1.351–11.672, P = 0.012), calf skinfold thickness (≥ 20.5 mm vs. < 20.5 mm, HR: 3.155, 95% CI 1.050–9.479, P = 0.041) and albumin level (< 33.6 g/L vs. ≥ 33.6 g/L, HR: 6.756, 95% CI 1.524–29.952, P = 0.012) were significantly associated with an increased risk of OS.
