CDC light traps underestimate the protective efficacy of an indoor spatial repellent against bites from wild Anopheles arabiensis mosquitoes in Tanzania

Table 2 Comparison of the different data collection methods in estimating protective efficacy against wild Anopheles arabiensis

	Method	IRR (95% CI)	P-value
Overall difference between collection methods	HLC	1
	Feeding	0.73 (0.25–2.12)	0.568
	CDC-LT	3.13 (1.57–6.26)	0.001
Within treatment	HLC	1
	Feeding	0.01 (0.01–0.04)	< 0.0001
	CDC-LT	1.43 (0.87–2.33)	0.158
Within control	HLC	1
	Feeding	0.02 (0.01–0.04)	< 0.0001
