Clinical events as a function of donor origin. (A) Event-free survival (EFS; apart from severe HPV infections). (B) Frequency of all clinical events over time (apart from severe HPV infections). (C) Prevalence of each event (inf. denotes infections other than HPV; autoim. inflam., autoimmunity and inflammatory events; nut.sup., persistent nutritional support). *A significant difference (P < .05) between recipients of a MSD HSC transplant and others according to Poisson regression model. (D) Change over time in the clinical score (mean clinical score and standard deviation for each category of patients are given in the y-axis), taking in account severe HPV infections or not.
