Days after LLINs installed (n)	Permethrin		Alfacypermethrin		P
Days after LLINs installed (n)	n	Mean mortality rate, % (± SD)	n	Mean mortality rate, % (± SD)	P
Day 1	15	84.1 (7.1)	15	79.4 (11.5)	0.158
Day 90	23	99.1 (3.3)	7	100.0 (0)	0.503

Day 540	15	93.9 (9.6)	15	94.7 (7.2)	0.790
Day 630	17	76.1 (12.6)	15	78.4 (15.0)	0.640
Day 720	16	44.8 (30.5)	14	73.2 (26.8)	0.012*

Study period: March 2012–February 2014
*Indicates a significant difference at P ≤ 0.05 in mean mortality rate between permethrin- and alfacypermethrin-impregnated LLINs at that time point
n = number of mosquitoes net evaluated
