Fig 1. Seropositivity by age for antibodies to three P. falciparum antigens in community members sampled during household surveys in Nacala-a-Velha and Mecubúri Districts, Northern Mozambique, 2013–2014.

Points represent estimates and 95% confidence intervals for seropositivity for each age category, curves represent the fit of a catalytic conversion model, and shaded areas represent the 95% confidence intervals of model fit: blue for 2013, red for 2014, and purple for the overlap.
