Fig 8. Chord diagram of the attributions associated with serious transfusion reactions.

Attribution to a category of relatedness is depicted by a line connecting from each serious transfusion reaction type. The width of each line and the circumferential axis indicate the number of patients in each combined serious transfusion reaction and relatedness category group. Other transfusion reactions that were adjudicated to be possibly related to the transfusion (n = 3) included leukomoid reaction (n = 1), pulmonary embolism (n = 1), and red cell dilution (n = 1). TACO, transfusion-associated circulatory overload; TRALI, transfusion-related acute lung injury.
