Area	Total number of home visits		Mean^1 percent of windows with our curtains present		percent of windows with our curtain present and used optimally		Percent^2 with ≤1 unscreened windows		Percent^2 with 2–4 unscreened windows		Percent^2 with ≥5 unscreened windows
	NTC	ITC	NTC	ITC	NTC	ITC	NTC	ITC	NTC	ITC	NTC	ITC
Urban/Suburban	1,258	1,203	79.2	81.6	50	50.5	35.1	21.4	19.1	20.5	45.8	58.1
