Does recombinant human erythropoietin accelerate correction of post-ulcer-bleeding anaemia A pilot study

Figure 1 Box-and-whisker plots showing a progressive increase of serum iron levels over the recovery period from peptic ulcer bleeding of patients treated with either Epoetin alfa plus iron (G₁, dashed whiskers) or iron only (G₂, open whiskers). There were not any statistically significant differences between treatment groups anytime during the study (two-tailed Mann-Whitney U test > 62, P > 0.67).

Figure 2 Box-and-whisker plots showing percent reticulocyte counts over the recovery period from peptic ulcer bleeding of patients treated with Epoetin alfa plus iron (G₁, dashed whiskers) and those treated with iron only (G₂, open whiskers). On day six patients in G₁ had significantly different (higher) median percent reticulocyte counts as compared with G₂ (two-tailed Mann-Whitney U test = 46.5, P = 0.03).

Figure 3 Box-and-whisker plots showing haematocrit values over the recovery period from peptic ulcer bleeding of patients treated with Epoetin alfa plus iron (G₁, dashed whiskers) and those treated with iron only (G₂, open whiskers). On day four-teen patients in G₁ had significantly different (higher) haematocrit values as compared with G₂ (two-tailed Mann-Whitney U test = 49.0, P = 0.041).
