Analysis of the CI, HI, BI, and number of PPI values obtained in autumn (April 2015; elevated vector densities due to higher temperatures) to spring (November 2015; low vector density due to low temperatures) in intervention and control clusters

	Intervention		Control		Difference in decrease (P value*)
	Baseline	Follow up	Baseline	Follow up
CI	5.15	0.97	7.54	1.83	1.52 (0.56) NS
HI	4.83	1.78	8.45	2.71	2.68 (0.30) NS
BI	7.09	1.89	10.72	3.07	2.45 (0.50) NS
PPI	0.110	0.010	0.050	0.013	−0.06 (0.042) S

A negative values means that the decrease in the intervention area was larger than in the control area.

BI = Breteau index; CI = Container index; HI = House index; NS: not significant; PPI = pupae per person index; S: significant.
