Modela	Slope	SE	Pb	Odd ratioc (95% CI)
IgG4 anti-RESA	0.250	0.093	0.006	2.7 (1.3–5.6)

IgG4 anti-MSP2-Nt	0.216	0.091	0.016	2.3 (1.2–4.8)
IgG4 anti-MSP2-Ct1	0.222	0.091	0.013	2.4 (1.2–5.0)
IgG4 anti-MSP2-Ct2	0.175	0.089	0.048	2.0 (1.0–4.0)

^aAge and hemoglobin genotypes were taken into account in each model. Six models were analyzed and corresponded to the Ags used. Ab levels were evaluated in sera taken at the end of the season of transmission (P2). 

^bThe P value was calculated by using the likelihood ratio criterion. 

^cThe odds between the lowest (IgG4 = 1) and the highest quintile (IgG4 = 5) are shown.
