Median concentration for the iron status biomarkers and CRP for the group of infants with Hb <110 g/L and the group with Hb ≥110 g/L at the age of 12 months
| Hb <110 g/L | Hb ≥110 g/L | P value | |
| Ferritin (µg/L) | 37 | 34 | 0.35 |
| Transferrin (g/L) | 2.6 | 2.7 | 0.08 |
| sTfR (mg/L) | 4.3 | 4.3 | 0.37 |
| Iron (µmol/L) | 8 | 10 | <0.001 |
| CRP (mg/L) | 1 | 1 | 0.32 |
Difference in distribution tested with Mann-Whitney U test.
CRP, C-reactive protein; Hb, haemoglobin; sTfR, soluble transferrin receptor.
