The need for blood transfusion was significantly different between the
three groups (P < 0.001). Pairwise comparisons (Table 3)
showed that the percentage of patients who required transfusion was
lower in non-anaemic patients compared to correctly treated patients
(2.2% vs. 24%, P < 0.001) and incorrectly treated patients
(2.2 vs. 26.5%, P < 0.001) but not between correctly and
incorrectly managed anaemic patients (P > 0.05).

incorrectly treated groups
