  1. Percentages refer to the proportion of participants who were followed for birth outcomes and are calculated from the column total
  2. A fisher's exact test was used to calculate the P value
  3. aAnemia was defined as a Hb level of < 11.0 g/dl during the first or third trimester or < 10.5 g/dl during the second trimester
  4. bIron deficiency and iron deficiency anemia were classified as having SF less than 15 μg/L and SF less than 15 μg/L and Hb level of < 11.0 g/dl during the first or third trimester or < 10.5 g/dl
