Fig. 3.

Correlations between hepcidin and iron status markers. Iron status markers include a) hemoglobin and b) serum ferritin from 21 Asian women participating in the Fe absorption study. Hepcidin and serum ferritin were transformed by natural logarithm. Black dashed lines represent the linear regression line. The correlations between iron status markers and hepcidin were significant: hemoglobin (p = 0.018, R² = 0.22), serum ferritin (p = 4.24e-08, R² = 0.79). Similar patterns were observed when using data from the screening day
