FIG 4.

IgG responses to merozoite antigens in relation to _molFOI and P. falciparum infection status. Children were divided into 3 groups (those with low, medium, and high _molFOI levels) to examine associations between antibody levels (OD) at baseline and _molFOI as a marker of exposure. As indicated, the presence of P. falciparum at baseline was determined by PCR. Data are presented as box-and-whisker plots (boxes show medians and interquartile ranges; error bars show 95% confidence intervals). Differences categorized by level of _molFOI are significant for AMA-1 and MSP2 responses among the PCR-positive children (P < 0.01).
