  1. Data are shown as number, mean ± standard deviation (SD) or median (range) for normally and non-normally distributed variables, respectively. MDS, myelodysplastic syndrome; cMPN, chronic myeloproliferative neoplasms; CLL, chronic lymphocytic leukemia; APACHE, acute physiology and chronic health evaluation; MV, mechanical ventilation; NIMV, non-invasive mechanical ventilation; ECOG, Eastern Cooperative Oncology Group. aOne patient with paroxysmal nocturnal hemoglobinuria cannot be included in this classification.
