Figure 2

Relative risk of in-hospital death due to blood transfusion in selected subgroups of ICU patients. Left panel demonstrates non-adjusted relative risks (RR). Right panel demonstrates relative risks adjusted to age, gender, comorbidities, severity scores on admission to the ICU, referring facility, type of surgery, the presence of sepsis syndromes, hemoglobin concentration on admission to the ICU, and the number of transfused units of blood. Blood transfusion was introduced in the model as a time-dependent variable in relation to the day on which blood transfusion was carried out. CI: confidence interval; SAPS: simplified acute physiology score; SOFA: sequential organ failure assessment.
