IgG response to gSG6-P1 and intensity of exposure to Anopheles gambiae sensu lato according to the studied sites. The medians of anti-gSG6-P1 IgG levels (Figure 3A) and the percentages of immune responders (Figure 3B) for all individuals (children and adults) are correlated to the number of An. gambiae bites/human/night according to districts. Black rhombus and black circles represent respectively median anti-sGS6-P1 IgG levels and percentage of human responders in the 16 CDs. The red solid line indicates the correlation line between each immunological parameter and the An. gambiae s. l. human biting rate. Statistical significant linear associations are indicated (simple linear regression method).
