Data are mean (SD) unless otherwise indicated. HC, head circumference.
One mother-infant pair was incorrectly instructed to follow directions for the EBF group and was therefore analyzed in that group.
CF n = 60; EBF n = 59.
One missing value.
Hb, MCV, and RDW n = 98; SF n = 94; TIBC n = 95.
Mean (SD) calculated with values from a blood sample taken 2 weeks later than 6 mo from 1 infant because some indices were inadvertently not examined on the first sample and were therefore examined on the second sample.
Data are median (interquartile range).
