Effect of placental infections as determined by thick blood smears on the level of anti-VSA antibodies. The MFIs of plasma were obtained and compared between women who presented with positive and negative placentas in (A) primiparous women and (B) multiparous women (≥ 2). The same comparisons was made between positive and negative placentas in (C) pauciparous women and (D) multiparous women (≥ 3). The data showed here were performed on the parasite Gb337. P values for each comparison are indicated in the graphs and the grand means of all MFI values for each group are shown as dashed lines. The center line in each diamond shows the group mean, and the vertical spans of the diamond show the 95% confidence interval.
