Table 3. Incidence of malaria parasite infection in net users and non–net users in low– and high–insecticide resistance clusters, Kenya, 2013 and 2014.

Parameter	No. children	Follow-up time, person-years	No. infections detected	Incidence, infections/person-year (95% CI)	Adjusted RR* (95% CI)	p value
Low resistance (mortality >82%)
Non–net users	175	15.6	63	4.0 (3.2–5.2)	1.00
Net users	760	182.9	415	2.3 (2.1–2.5)	0.61 (0.42–0.88)	0.01
High resistance (mortality <82%)
Non–net users	129	9.0	48	5.3 (4.0–7.1)	1.00
Net users	772	167.7	494	2.9 (1.7–3.2)	0.55 (0.35–0.87)	0.01
Interaction parameter					0.86 (0.48–1.55)	0.63
Change in incidence per 10% increase in mosquito mortality					0.96 (0.87–1.06)	0.45

*Adjusted for district, year, and visit month.
