Temperature, mosquito feeding status and mosquito density influence the measured bio-efficacy of insecticide-treated nets in cone assays

Table 2 Effect of mosquito feeding status on An. funestus mortality measured on cone bioassays

Feeding status	n	24 h mortality		48 h mortality		72 h mortality
Feeding status	n	OR^a (95% CI)	P value	OR^a (95% CI)	P value	OR^a (95% CI)	P value

CI Confidence interval, ITN insecticide-treated net, n number of replicates, OR odds ratio
^aThe ORs were derived from mixed-effects logistic regression adjusted for net type, cone replicate, experimental time and day of the experiment, with observation was included as a random effect
