Mean change in a Hb, b FER, c sTfR, d RBP, and e folate concentrations from baseline to 5 months (follow-up) by group and status at baseline. A general linear model with adjustments for baseline values was used to predict marginal mean changes (95% CIs) for each outcome variable. Whiskers illustrate corresponding 95% CIs. a Mean change of Hb for subjects with moderate anemia (Hb ≥8.0 and < 11.0 g/dL), mild anemia (Hb ≥11.0 and < 12.0 g/dL), and no anemia (Hb ≥12.0 g/dL) at baseline. Total n = 85/n = 85 (intervention/control). b Mean change of FER for subjects with iron deficiency (FER < 15 μg/L), marginal iron stores (FER ≥15 and < 50 μg/L), and sufficient iron stores (FER ≥50 μg/L) at baseline. Total n = 84/n = 84. Values adjusted for subclinical inflammation. c Mean change of sTfR for subjects with iron deficiency, marginal iron stores, and sufficient iron stores at baseline. Total n = 84/n = 84. d Mean change of RBP for subjects with marginal VitA deficiency (RBP ≥0.70 and <1.05 μmol/L) and no VitA deficiency (RBP ≥1.05 μmol/L) at baseline. Total n = 84/n = 84. Values adjusted for subclinical inflammation. e Mean change of folate for subjects with marginal folate deficiency (folate ≥3 and < 6 ng/mL) and no folate deficiency (folate ≥6 ng/mL) at baseline. Total n = 78/n = 73. Hb: Hemoglobin; FER: Ferritin; sTfR: Soluble transferrin receptor; RBP: Retinol binding protein; VitA: Vitamin A.
