Results of the logistic regressions testing the effect of different ecological factors on the ape Plasmodium infection rate

Variable	Odds ratio (95% CI)	P value
Species
An. moucheti	0.60 (0.068–5.23)	0.642
An. vinckei	15.16 (4.81–47.82)	3.61 × 10−6
Rainy season	3.49 (1.076–11.35)	0.0374
Midheight	1.94 (0.98–3.83)	0.0560
Canopy	0.50 (0.144–1.73)	0.2742

The variable to be predicted was the presence of an ape Plasmodium infection. For species, the predictive variable (fixed effect) was the Anopheles species. For season and height, the predictive variables were the height of collection (three modalities: ground, midheight, and canopy) and the season (two modalities: dry season or rainy season).
