Fig. 4
The association between the number of malaria episodes in pregnancy and small-for-gestational-age (SGA). Numbers are odds ratios with 95% confidence intervals. See Additional file 4 for a table version of this figure. The associations between the number of episodes and loge(odds) were linear for falciparum malaria (p = 0.819) and vivax malaria (p = 0.118). SGA was missing in 2636 [5%] (no malaria 2078 [5%]; malaria 558 [7%])
