| Modela | Slope | SE | Pb | Odds ratioc (95% CI) |
|---|---|---|---|---|
| IgG2 anti-RESA | −0.337 | 0.130 | 0.010 | 0.26 (0.09–0.72) |
| IgG2 anti-MSP1-Nt | −0.127 | 0.124 | NS (0.304) | |
| IgG2 anti-MSP2-Nt | −0.272 | 0.128 | 0.033 | 0.34 (0.12–0.92) |
| IgG2 anti-MSP2-Ct1 | −0.286 | 0.128 | 0.025 | 0.32 (0.12–0.87) |
| IgG2 anti-MSP2-Ct2 | −0.237 | 0.130 | NS (0.060) | |
| IgG2 anti-extract | −0.152 | 0.133 | NS (0.252) |
a
Age was taken into account in each model. Ab levels were evaluated in sera taken at the end of the season of transmission.
b
The P value was calculated by using the likelihood ratio criterion.
c
The odds between the lowest (IgG2 = 1) and the highest quintile (IgG2 = 5) are shown.
