  1. This table presents the Generalized linear model obtained through the control variables bednet use, sex, and HbS. The reference groups corresponded to the low level of IgG3 specific to each merozoite antigen determined according to the median. IgG1 to merozoite P. falciparum antigens were quantified at 18 months of age
