Figure 2. Neonatal FABP4 levels inversely correlated with blood glucose and are elevated among hypoglycemic neonates.

Figure 2

Serum samples collected from 21 normoglycemic and 29 hypoglycemic neonates (as detailed in Table 2) within the first few hours of life. (A) FABP4 circulating levels in neonates were correlated with blood glucose levels. Comparison of serum FABP4 between 31 normoglycemic and 28 hypoglycemic neonates is presented in (B). (C and D) C-peptide circulating levels in neonates were compared and analyzed between normoglycemic (n = 10) and hypoglycemic (n = 13) neonates (D) and insulin circulating levels in neonates were compared and analyzed between normoglycemic (n = 19) and hypoglycemic neonates (n = 21) (C). Statistical analysis was performed by nonparametric correlations using Spearman’s correlation test (A) and by Student’s t test (B–D). Data are shown as the mean ± SEM. *P < 0.05.
