Variables are reported as number (percentage) or median [IQR].
* For ICU parameters, only patients who stayed at the ICU of the institute (n = 51) were described (3 patients transferred in other ICUs were excluded from the analysis, since information regarding ICU treatments was not available).
**Total effective of 53 patients (vital status not known for 1 of the patients transferred to another hospital), HSCT: Hematopoietic stem cell transplantation.
