Text: In intention-to-treat analysis, comparison of women who received iron vs placebo, respectively, yielded the following results at birth : Plasmodium infection risk : 50. 9 % vs 52. 1 % (crude difference, -1. 2 %, 95 % CI, -11. 8 % to 9. 5 % ; P =. 83) ; birth weight : 3202 g vs 3053 g (crude difference, 150 g, 95 % CI, 56 to 244 ; P =. 002) ; birth-weight-for-gestational-age z score : 0. 52 vs 0. 31 (crude difference, 0. 21, 95 % CI, -0. 11 to 0. 52 ; P =. 20) ; and at 1 month after birth : maternal hemoglobin concentration : 12. 89 g/dL vs 11. 99 g/dL (crude difference, 0. 90 g/dL, 95 % CI, 0. 61 to 1. 19 ; P <. 001) ; geometric mean maternal plasma ferritin concentration : 32. 1 g/L vs 14. 4 g/L (crude difference, 123. 4 %, 95 % CI, 85. 5 % to 169. 1 % ; P <. 001) ; geometric mean neonatal plasma ferritin concentration : 163. 0 g/L vs 138. 7 g/L (crude difference, 17. 5 %, 95 % CI, 2. 4 % to 34. 8 % ; P =. 02).
