Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:However, those results present several limitations and raise several questions. In our longitudinal cohort, the risk of death reaches 80% and 64% for myeloid neoplasm and plasma cell neoplasm, respectively, that is twofold higher than reported in previous studies.1 We must point out a higher COVID-19 severity with 34% of patients with myeloid and plasma-cell neoplasm requiring for mechanical ventilation whereas only 13% for B-cell neoplasm at the time of CCP. Similarly, previous studies reported a better outcome after early CCP transfusion in non-hospitalized patients.21 Of note, we observed a lower overall survival in patients transfused within the first ten days after symptoms onset in univariable analysis, an association that disappeared in the multivariable analysis. A similar observation was made in the Recovery trial (in the CCP arm as well as the control arm) and may reflect more severe disease in patients hospitalized early in the course of the disease.22 Furthermore, 62% of patients transfused earlier (within the first ten days) transfusion in our cohort presented with myeloid or plasma-cell neoplasm. In our retrospective nested analysis, data were collected prospectively from two data sources: one for patients exposed to CCP and another one for patients not exposed to CCP. Such comparison could not identify causal effect of treatment exposure with the level of proof provided by randomized clinical trials. We have tried to limit bias by using statistical methods to c...
