Among patients with early diffuse cutaneous systemic sclerosis, HSCT was associated with increased treatment-related mortality in the first year after treatment. [ncbi.nlm.nih.gov]
Seventy-five patients in each group started treatment. Six patients did not receive the allocated treatment, whereas 71 (89.8%) and 57 (74.0%) completed treatment in the HSCT and cyclophosphamide groups, respectively ( Figure 1 ). [doi.org]
