Anti- Plasmodium falciparum schizont IgG levels in July 2003. A comparison of anti-Plasmodium falciparum schizont IgG antibodies in 290 children surveyed in December 2002 (panel A) and in 305 children surveyed in July 2003 (panel B) by parasite status. All children had received IPT or placebo in September, October and November. The P value between the IPT and the control groups originates from a multivariate analysis (see Table 1) whereas Mann-Whitney tests were used to compare Plasmodium carriers to non-carriers. Bars indicate the median value for each sub-group.
