Fig. 1

Associations of the extremely 10th percentile of serum concentrations of iron-related indicators with neonatal anthropometric indicators, including: (A) femur length, measured by B-mode ultrasound nearest delivery; (B) birth weight; (C) body length; (D) head circumference; and (E) chest circumference. Analyses of covariance were used to compare the differences between groups of < 10th, 10th-90th, and > 90th percentiles of serum concentrations of iron-related indicators, after adjusting for potential covariates. Data were presented as adjusted means. Error bars in the figure presented standard errors. Multiple comparisons among groups were adjusted using Bonferroni correction. *: P < 0.05; **: P < 0.01; ***: P < 0.001
