Probability of DFS.

Six-year probability of DFS according to the development of cGVHD is shown for patients affected by nonmalignant disorders (A) and for those affected by hematologic malignancies (B). The difference was not statistically significant for nonmalignant disorders, whereas in the group of patients affected by malignant diseases, the advantage for subjects with cGVHD was statistically significant (P = .0013).
