Table 4 Correlation of haemoglobin (Hb), serum iron (SI) and serum ferritin (Sf) of babies in both groups with breast milk iron (BMi) and breast milk lactoferrin (BML)

From: A prospective study of iron status in exclusively breastfed term infants up to 6 months of age

Variable   Group A   Group B
  r-value Regression equation r-value Regression equation
Hb vs BMi* 0.863 Hb = 9.659+8.236 × BMi 0.876 Hb = 8.971+8.578 × BMi
SI vs BMi* 0.808 SI = 50.511+100.496 × BMi 0.802 SI = 40.637+119.438 × BMi
Sf vs BMi* 0.912 Sf = -9.932+159.375 × BMi 0.910 Sf = -9.032+161.766 × BMi
Hb vs BML* 0.812 Hb = 8.825+0.607 × BML 0.772 Hb = 8.485+0.489 × BML
SI vs BML* 0.793 SI = 26.205+9.087 × BML 0.680 SI = 21.473+8.766 × BML
Sf vs BML* 0.795 Sf = -22.825+11.207 × BML 0.811 Sf = -32.277+11.691 × BML
  1. *p-value < 0.001 (simple regression analysis).
  2. Group A- non-anemic mothers and their babies.
  3. Group B- anemic mothers and their babies.
