Changes in hepcidin levels and associations with serum iron and TSAT in the first week of life. Left-hand panels: Distributions of log-hepcidin levels at each time point. Right-hand panels: Scatterplots of TSAT and serum iron against log-hepcidin. Lines indicate the best fit from quadratic regression. TSAT vs Log-hepcidin: CDV R² = 0.068, 246 degrees of freedom (DF), V1 R² = −0.037, 265 DF, V2 R² = −0.003, 51 DF, V3 R² = −0.050, 86 DF, V4 R² = −0.084, 56 DF. Serum iron vs log-hepcidin: CDV R² = 0.035, 251 DF, V1 R² = −0.056, 265 DF, V2 R² = −0.019, 51 DF, V3 R² = −0.037, 88 DF, V4 R² = −0.000, 58 DF.
