Target number of participants 406 in each treatment arm (812 in total)
Interventions Through an open label block randomisation (block size of 20); women were assigned to receive one of the treatment regimens (two or three doses of SP). One treatment dose was 1500 mg of sulfadoxine and 75 mg of pyrimethamine. Sequence of dosing admistration was as follows:
1. Women in the three-doses received the first dose between the 4th - 6th month of gestation, the second dose between 5th - 7th month of gestation, and the third dose no later that the 8th month of gestation
2. Women in the two-dose group received the first dose between the 4th - 6th month of gestation and the second dose no later than the 8th month of gestation. Doses were administered at least one month apart.

All drugs were administered directly by the study team and women were observed for 30 minutes following dosing. Study participants were asked to avoid self medication of anti-malrials other than the study medication and to return to the clinic for scheduled monthly assessment or any unscheduled sick visits. Women received ferrous sulphate (200 mg containing 60 mg of iron) and folic acid (0.4 mg) daily starting two weeks after each SP dosing as recommended by the Ministry of Health.

If malaria was diagnosed during subsequent visits, oral quinine was given 600 mg three times a day over 7 consecutive days.
Primary outcome measure(s) Placental malaria. Placental blood was collected from the maternal side of the placenta (after cleaning using filter paper before cutting with cleaned lancet) for thick blood smear for parasitaemia detection.
Secondary outcome measure(s) 1. Low birth weight. Gestational age at delivery was assessed using the Ballard score, and infants were weighed using a digital scale within 24 hours of delivery to measure the incidence of low birth weight.
2. Maternal anaemia. Following delivery, haemoglobin concentration was measured by HemoCue® (Hemocue 201: Anglholm, Sweden) and peripheral parasitaemia was assessed by peripheral blood smear.
