Table 3 Summary findings of tests for effects of varying distances between traps and huts (with or without transfluthrin-treated eave ribbons) on Anopheles arabiensis outdoor-biting and indoor-biting risk observed in the evaluation of push–pull
Distance | N | Indoor biting risk (assessed using CDC-light trap) | Outdoor biting risk (assessed using human landing catch) | Mosquitoes trapped | ||||||
|---|---|---|---|---|---|---|---|---|---|---|
Mean (95% CL) | RR (95% CI) | % Protection | p-value | Mean (95% CL) | RR (95% CI) | % Protection | p-value | Mean (95% CL) | ||
