8. Vector density: ITS versus no intervention.

Trial ID	Unit of randomization	Intervention	Main vector	Measure (method)	Pre‐intervention		Post‐intervention		Effect measure (95% CI) or P value
					ITS	Control	ITS	Control
Kelly 1997 BRA	Chicken sheds	Sheets impregnated with lambdacyhalothrin (20 mg/m²) installed 1 meter from the chicken shed.	Lu. longipalpis	Geometric mean sandflies (light traps)	622.3 (October 1993)	404.6 (October 1993)	Not reported	Not reported	The trial authors state "the abundance in sheds was approximately 50% below that expected on the first day falling to about 80% at week 12 ‐ the only time the difference was statistically significant".

Abbreviations: BRA = Brazil: ITS = insecticide treated sheet.
