Table 4 The adjusted odds ratio of mosquito landings and protective efficacy offered by EC and TG transfluthrin in the semi-field system, Bagamoyo, Tanzania

From: Transfluthrin eave-positioned targeted insecticide (EPTI) reduces human landing rate (HLR) of pyrethroid resistant and susceptible malaria vectors in a semi-field simulated peridomestic space

  1. aNumbers in the control and treatment refer to the total number of mosquitoes caught/released during each experiment; the percentage recaptured is in bracket. The percentage landing was calculated by dividing the number recaptured (n) by the total released (N = 1280). The ORs are adjusted for temperature, humidity, compartment, volunteers and all other factors in the table
