An experimental hut study to quantify the effect of DDT and airborne pyrethroids on entomological parameters of malaria transmission

Table 3 Total mosquitoes that entered untreated huts that previously had insecticides (experimental nights; n = 12)

Treatment	N	Median	IQR	RR	95% CI	z value	p value
No insecticide	1054	47.0	22.0 – 110.3	45.0	[23.1, 87.8]	11.168	NA
Transfluthrin coils	737	71.0	28.0 – 92.5	41.1	[33.6, 50.2]	-0.897	0.369
Metofluthrin coils	877	67.0	39.8 – 103.0	51.1	[42.0, 62.3]	1.273	0.203
DDT 2gm²	821	42.5	37.5 – 72.3	44.9	[36.8, 54.8]	-0.014	0.989

Legend: This table illustrates indoor mosquito densities in huts that previously had coils and DDT. The mosquitoes were collected during the wash period when the huts had no insecticides.
N = Total number of mosquitoes; Median = Number of mosquitoes per hut per night; IQR – Interquartile range; RR – Relative rate CI = Confidence intervals.
