Table 2. Generalized linear model analysis of 2h pyrethroid insecticide exposure; CDC bottle bioassay data for collections from Tabtenga.

Source	Wald χ21	P-value	Mortality difference
Intercept	33.6	<<0.001
Container	31.2	<<0.001	tire > drum
Insecticide	33.1	<<0.001	deltamethrin > permethrin
PBO	246.2	<<0.001	PBO > no PBO

The model includes container type, pyrethroid insecticide type and pre-exposure to a synergist as factor. All interaction terms were included initially but were non-significant and the minimal model is shown
