Survival after salvage treatment. Probabilities of a patient being alive in the original complete (CR) or partial remission (PR) or in a subsequent remission because of salvage therapy after the nonmyeloablative allograft (A) or the second autograft (B) calculated by the Couper method (dotted line). Black and gray solid lines represent overall (OS) and event-free survival (EFS) by the Kaplan-Meier methods (see “Long-term clinical outcomes”). (C) OS, calculated from first relapse, of patients who relapsed after the nonmyeloablative allograft (solid line) and after the second high-dose melphalan autograft (dotted line).
