  1. **The continuous variables were compared using the Mann–Whitney U-test, and the differences in frequency between the two groups were compared using the chi-square test. The criterion for statistical significance was P < 0.05
  2. aGroup matching criteria included age at HSCT (±1years), pre-HSCT cycles of chemotherapy (±1cycle), disease status at HSCT, and BM microenvironment evaluated time after HSCT (±5 days). For each case, two GGF control was randomly selected from the same cohort at which the PT occurred (risk-set sampling)
