Blood Transfusion, Serum Ferritin, and Iron in Hemodialysis Patients in Africa

Figure 1

Correlation between (a) serum ferritin and the number of blood transfusions: the graph shows strong positive linear relationship between the number of blood transfusions and high serum ferritin in hemodialysis patient (Spearman ; value: 0.0001); (b) serum iron and the number of blood transfusions: the graph shows a weak association between the number of blood transfusions and serum iron concentrations (Spearman ; value: 0.04); (c) serum ferritin and serum iron: the graph shows a weak association between serum ferritin and serum iron (Spearman ; value: 0.003).
