Incidence of severe malaria in Tanzanian children from birth to 12 months of age, dichotomized into those with the highest 10% (n = 64) and lowest 90% (n = 583) levels of anti–PfSEA-1 IgG in cord blood. Bars represent the incidence of severe malaria after adjustment for age, age², parity, average prior parasitemia, and repeated measures within individuals in GEE models. Error bars represent SEM. (A) Total IgG anti–PfSEA-1. (B) IgG₁ anti–PfSEA-1. Abbreviations: GEE, generalized estimating equation; IgG; PfSEA-1, Plasmodium falciparum Schizont Egress Antigen-1; SEM, standard error of the mean.
