Figure 3From: Age-adjusted Plasmodium falciparum antibody levels in school-aged children are a stable marker of microgeographical variations in exposure to Plasmodiuminfection Age profiles of Pfs-IgG3 levels during low and high transmission seasons. (A) Longitudinal comparisons of mean +/- 2 standard errors low transmission season (circles) and high transmission season (squares) Plasmodium falciparum schizont Ag (Pfs)-IgG3 levels of individuals who participated at both time points (n = 684), stratified by age. Paired t-tests found no significance between low and high malaria transmission season Pfs-IgG3 levels for any age group. (B) Cross-sectional age-related curves of low transmission (circles, solid line; n = 1044) and high transmission (squares, dashed line; n = 973) Pfs-IgG3 levels; bars represent +/- 2 standard errors.Back to article page
