Figure 4. The placental score differentiates the women who were exposed to P. vivax during pregnancy.

Figure 4

A score (termed the ‘vivax-score’) was developed and applied to all of the placental samples in this study (see main text for details). (A) The placental samples from the “no Plasmodium” group (n = 41, white box) revealed a significantly lower score than the placentas from the “P. vivax” group (n = 59, red box) (* Mann-Whitney, P = 0.027). (B) The vivax-score increased significantly (** Cuzick's trend test: z = 2.76, P = 0.006) with increased exposure to P. vivax during pregnancy. “No infection”, n = 41; “1 infection”, n = 39; “2+ infections”, n = 20).
