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).
