Figure 2.
Improvement in survival over time. Five-year survival is depicted for all patients (first row), responders to immunosuppressive therapy (IST) (second row), and non-responders to IST (third row). Six-month survival, as a surrogate for neutropenia, in non-responders to IST is presented in the fourth row. The first column depicts hematopoietic stem cell transplantation (HSCT)–censored Kaplan-Meier survival curves and the second column HSCT non-censored curves. Overall survival for all patients was improved in group 3 (first row) compared with groups 1 and 2. Among responders to immunosuppressive therapy, no difference in survival was noted over time (second row). Among non-responders, a marked improvement in survival occurred in group 3, compared with survival in groups 1 and 2 (third row). The 6-month survival after IST among non-responders was also markedly higher in group 1 than in group 3 (fourth row).
