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).
