*Daily intake of 400 μg of folic acid and received iron (120 mg) if their haemoglobin was <9 g/dL. †Daily intake of 60 mg of ferrous sulphate plus 400 μg of folic acid. ‡Frequency and percentage of women at recruitment who attended subsequent visits. §The denominator is the number of those who attended at each subsequent visit.
