(A) Single-patient representation of number of relapses in the 12 previous months (full dots, ntot = 16) and in the 12 months after BM-MSC infusions (shaded dots, ntot = 15) shown overall (purple, left panel), in children (blue, central panel), and in adults (red, right panel). Data were compared by Wilcoxon’s test. **P < 0.01. NS, not significant. †One adult patient was lost to follow-up at +8 months, as detailed in Supplemental Table 2. (B) Single-patient representation of number of immunosuppressive drugs at baseline (full dots, ntot = 16) and at +12 months after BM-MSC infusions (shaded dots, ntot = 15) shown overall (purple, left panel), in children (blue, central panel), and in adults (red, right panel). Data were compared by Wilcoxon’s test. *P < 0.05, **P < 0.01. NS, not significant. †One adult patient was lost to follow-up at +8 months, as detailed in Supplemental Table 2.
