Figure 2.
Outcome of patients in the first year after allogeneic stem cell transplantation and after onset of acute graft-versus-host disease when stratified according to pre-transplant asymmetric dimethylarginine quartiles. (A, B) Higher pre-transplant asymmetric dimethylarginine (ADMA) serum levels were associated with lower probabilities of overall survival (OS) in (A) the first year after allogeneic stem cell transplantation and (B) after the onset of acute graft-versus-host disease (GvHD). (C, D) The probabilities of progression-free survival (PFS) in (C) the first year after transplantation and (D) after the onset of acute GvHD were substantially lower in patients with higher pre-transplant ADMA levels. (E, F) Higher pre-transplant ADMA serum levels were associated with higher incidences of non-relapse mortality (NRM) in (E) the first year after allografting and (F) after the onset of acute GvHD. (G) In contrast, the ncidence of relapse during the first post-transplant year was not affected by pre-transplant ADMA levels. Note: Quartiles were chosen for reasons of visualization of the continuous ADMA effect which was observed for every 2-fold change in multivariable analyses (Tables 2 and 3). For this reason, and since pre-transplant ADMA values were not normally distributed, there is an overlap of the second and third quartile. Q1-4, quartiles of the ADMA distribution.
