Prevalence and levels of antibody responses to PfMSP5 in the three cohorts.

*Individuals with positive IgG response = ODratio>2 ie > OD of naive control + 2SD. **Younger individuals : in Dielmo ie <7 years old; in Ndiop ie <15 years old.* IgG抗体阳性反应个体：光密度比值（ODratio）＞2，即大于未致敏对照（naive control）的光密度值与2倍标准差（2SD）之和。 ** 低龄受试者：在迪耶尔莫（Dielmo）研究现场，指年龄小于7岁的个体；在恩迪奥普（Ndiop）研究现场，指年龄小于15岁的个体。
