Figure 1. Antibody levels at study inclusion and delivery, by parity, against placental malaria in pregnant women, Benin. A) Apical membrane antigen 1 (AMA-1); B–F) Duffy binding-like (DBL) antigen; G) Full-length ectodomain of variant surface antigen 2 chondroitin sulfate (FV2); H) Variant surface antigen (VSA). Solid circles indicate medians for inclusion, solid squares indicate medians for delivery, and error bars indicate interquartile ranges. AU, absorbance units; rMFI, relative median fluorescence intensity. *Parity dependence at inclusion (p<0.05 by Fisher exact test). †Parity dependence at delivery (p<0.05 by Fisher exact test). ‡Decrease between inclusion and delivery (p<0.05 by paired Wilcoxon test). §Increase between inclusion and delivery (p<0.05 by paired Wilcoxon test).
