Fig. 5 — Kaplan–Meier estimates of relapse-free survival of 45 autoimmune thrombotic thrombocytopenic purpura (iTTP) patients with a first disease bout since 2003. Relapse-free survival of iTTP patients receiving rituximab ( n = 17) (upper dotted curve) compared with iTTP patients who did not receive rituximab ( n = 28) (lower curve) during their first acute thrombotic thrombocytopenic purpura (TTP) bout. Vertical bars denote censored patients not having suffered from relapse. There was no statistical difference between these groups ( p -value = 0.131).
