 Comparison of transfusion variables across diagnostic groups using one way analysis of variance

Diagnostic categoryPre-transfusion Hb (g/dl)*Post transfusion Hb (g/dl)*Delta Hb (g/dl)**Transfusion volume of packed cells (ml/kg)**Delta Hb/(vol/kg)
Data shown are mean and 95% CI for each diagnostic group. Only data from children without confounding variables are included (n = 82). A single haematology/oncology case is omitted from the table as the group size is too small. *p<0.001. **p<0.01.
