Antibodies (Abs) to Duffy antigen-binding ligand (DBL) domains in primigravidae at delivery. Ab levels at delivery (or last visit during the third trimester) were measured in primigravidae before (N = 18) and after (N = 27) intermittent preventive treatment (IPT) (median fluorescence intensity [MFI], interquartile range). All women in the IPT group received at least one dose of sulfadoxine–pyrimethamine. Statistical analysis: two-sample t test with unequal variances. After taking multiple comparisons into consideration for the six DBL domains, the differences remained significantly reduced.
