Proportion of patients with events, over time and aggregation of these events. (A) The frequency of events over time is represented. Numbers of patients for each time point are given under the x-axis. (B) The frequencies of severe HPV infections and all events other than HPV infections are plotted separately, showing a decreased incidence of events over time and a progressive increase in severe HPV infections. Numbers of patients for each time point are given under the x-axis. (C) Aggregation of clinical events: nutritional support, autoimmunity/inflammation, persistent cGVHD, and opportunistic infection: n = 3; persistent nutritional support and autoimmunity/inflammation: n = 4; autoimmunity/inflammation and persistent cGVHD: n = 1; persistent nutritional support and persistent cGVHD: n = 2. Severe HPV infections and nonopportunistic infections: n = 2; growth failure: n = 15. *Death (individual cases).
