The hematology for study children at 10-year follow up is shown by infant iron status group.
a
Infant iron status group is defined as:
- IDA-6: Infants whose iron deficiency anemia status was identified at 6 months but were iron sufficient at 12 or 18 months.
- IDA-12: Infants whose iron deficiency anemia status was identified at 12 months but were iron sufficient at 6 or 18 months.
- IS: Randomly selected formerly non-anemic infants.
b
NObs: Total number of children in each iron status group.
c
Mean and standard deviation (SD) are shown for the following hematology measures: hemoglobin (Hb); mean corpuscular volume (MCV); free erythrocyte protoporphyrin (FEP); and plasma ferritin (Ferritin).
d
N: Number of blood samples available.
e
ID (n, %): The number and percent of subjects that are ID at 10 years of age.
