sMICA distribution profile among patients and cumulative incidence for cGVHD based on sMICA serum levels after transplantation. (A) The analysis of the distribution profile of post-HSCT sMICA allowed us to pinpoint a cutoff at the 70th percentile. (B) Patients having sMICA serum level greater than 80 pg/mL after transplantation are those at high risk of developing cGVHD (univariate analysis).
