Text: Supplementation reduced both the risk of a birth size that was small for gestational age (< 10th percentile ; 10. 7 % in the multivitamin group vs. 13. 6 % in the placebo group ; relative risk, 0. 77 ; 95 % CI, 0. 68 to 0. 87 ; P < 0. 001) and the risk of maternal anemia (hemoglobin level, < 11 g per deciliter ; relative risk, 0. 88 ; 95 % CI, 0. 80 to 0. 97 ; P = 0. 01), although the difference in the mean hemoglobin levels between the groups was small (0. 2 g per deciliter, P < 0. 001).
