TABLE 5.
Specific IgG4 levels and risk of infection
| Modela | Odds ratiob (95% CI) for IgG2 quintile:
|
||
|---|---|---|---|
| IgG2 = 1 | IgG2 = 2 | IgG2 = 3 | |
| IgG4 anti-RESA | 13.5 (5.4–34.3) | 5.9 (2.7–13.0) | 2.6 (1.2–5.6) |
| IgG4 anti-MSP1-Nt | 12.6 (4.6–34.4) | 4.7 (1.9–11.4) | NS |
| IgG4 anti-MSP2-Nt | 10.3 (4.4–23.9) | 4.6 (2.2–9.4) | NS |
| IgG4 anti-MSP2-Ct1 | 9.8 (4.1–23.2) | 3.6 (1.7–7.7) | NS |
| IgG4 anti-MSP2-Ct2 | 12.3 (5.0–30.3) | 4.6 (2.2–9.9) | NS |
| IgG4 anti-extract | 10.9 (4.4–27.0) | 5.2 (2.4–11.4) | 2.5 (1.1–5.5) |
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 odds between the lowest (IgG4 = 1) and the highest quintile (IgG4 = 5) are shown for three IgG2 quintiles (IgG2 = 1, 2, and 3). The odds were not significant for the other IgG2 quintiles (IgG2 = 4 and IgG2 = 5).
