Patient grouping
A total of 278 patients with gastrointestinal bleeding were studied. Out of these, only 81 required transfusions. Transfusion-associated circulatory overload (TACO) was identified in 10 cases (T-group); within this group only 3 cases also had liver cirrhosis (TL-group). Of the transfused patients, 71 had no evidence of TACO and 27 had liver cirrhosis. Patients without TACO and without liver cirrhosis were used as a second control (n=44).
