Values are means (SD). Significant group differences based on the final iron status classification (p < .05) are indicated by superscripts as follows:
a
IDA differs from IS,
b
IDA differs from NA ID,
c
NA ID differs from IS. The significant differences based on the provisional iron status classification were the same as for the final classification, with one exception: NA ID and IDA groups did not differ in ZPP/H.
