r_s = Spearman correlation, BAZ = BMI-for-age z-score, WAZ = Weight-for-age z-score, HAZ = Height-for-age z-score, TfR = Transferrin receptor, CRP = C-reactive protein, ZnPP = Zinc protoporphyrin, RBC = red blood cell, WBC = white blood cell, MCV = Mean cell volume, Hb = Hemoglobin.

^**Correlation coefficient is significant at the 0.01 level (2-tailed).

^*Correlation coefficient is significant at the 0.05 level (2-tailed).
