Table 2 Duration of Anopheles arabiensis physical contact with a bed net, during a 60-min test

Duration of physical contact with the bed net surface (60 min test)
	Mean total time (all contacts)^a (min)	Mean time/mosquito (10 mosquitoes)^b (s)	Mean time/mosquito (observed max number)^c (s)
Untreated net	33.9 (15.78–52.1)	204	290
LLIN	7.75 (4.43–11.05)	46	82

Table shows net contact duration as calculated for ^a the mean total time of all contacts observed (all mosquitoes); ^b the minimum mean contact time per mosquito, assuming all 10 mosquitoes responded, and ^c the calculated maximum mean contact time per mosquito, based on the maximum number of individual mosquitoes observed simultaneously at any time in each test. Values shown are means with 95% CI
Mean total contact time was significantly higher at untreated nets than at LLINs (p = 0.010)
