Best mixed-effects model for total hemoglobin and lactate dehydrogenase during delayed hemolytic transfusion reaction, before and after anti-C5 antibody infusion. Hemoglobin (Hb) levels are predicted for a “theoretical” patient receiving anti-C5 antibody infusions on days 0 and 7 and no packed red blood cell (pRBC) transfusions. Before anti-C5 antibody infusion, basal total Hb concentration in this model was 51.0 g/L (the intercept of the model), with an increase of +3.8 g/L for each pRBC unit transfused, and ongoing hemolysis at a rate of -4.4 g/L for each passing day (the fixed effects of the model). However, after anti- C5 antibody infusion, Hb levels gradually increased, with a basal Hb concentration of 46.2 g/L: the effect of each transfusion was an increase of 1.58 g/L for each pRBC unit transfused and an increase in Hb levels of 0.94 g/L.
