Text: Twelve weeks of therapy with recombinant erythropoietin and oral iron increased mean (+ / - SE) hemoglobin concentrations from 8. 81 + / -0. 27 g per deciliter (5. 47 + / -0. 17 micromol per liter) to 10. 52 + / -0. 41 g per deciliter (6. 5 + / -0. 25 micromol per liter), whereas hemoglobin concentrations in the placebo group decreased from 8. 69 + / -0. 11 g per deciliter (5. 4 + / -0. 068 micromol per liter) to 7. 84 + / - 0. 33 g per deciliter (4. 9 + / -0. 2 mmol per liter) (P < 0. 001).
