Antibody levels to VAR2CSA domains stratified by gravidity. Levels at enrollment (a), gestational week 30–32 (b), and delivery (c) among primigravid (P, brown boxes), secundigravid (S, blue boxes) and multigravid (M, red boxes) women. Numbers that follow indicate the number of samples at enrollment, gestational week 30–32 and delivery in each gravid group: primigravidae (n = 157, 109, 152); secundigravidae (n = 118, 83, 114); multigravidae (n = 328, 245, 324). Significant differences between primigravidae and multigravidae are indicated with †, between primigravidae and secundigravidae with *, and between secundigravidae and multigravidae are indicated with §. The results are expressed as median fluorescent intensity (MFI). Box plot indicates the median (horizontal line) and interquartile range (box), the whiskers indicate the 10th and 90th percentiles
