Although post-transplant CRP and ferritin levels were well correlated with sST2 (Table 2), these markers did not influence the cumulative incidence of acute GVHD (cut-off values were calculated by ROC analysis=CRP 6.0 mg/dL and ferritin 1700 mg/dL, respectively) (Figure 5B and Figure S1, B). The gene discussed is CRP; the disease is acute graft versus host disease.
