Baseline clinical features of the research cohort
isohemagglutinins
The baseline clinical features of the training and validation cohorts are depicted in Patients’ baseline features.Minor ABO mismatch demonstrated the donor had isohemagglutinins against the recipient’s red blood cells, including the following blood group combinations: O (donor) into A, B, or AB (recipient); A or B (donor) into AB (recipient) (recipient). Major ABO mismatched indicated that the recipient had isohemagglutinin resistant to donor red blood cells and included the following blood group combinations: A, B, or AB (donor) became O (recipient), and AB (donor) became A or B (recipient). Major-minor mismatched suggest that both the donor and the recipient share isohemagglutinins: A to B and vice versa.
