Table 1. Associations between the logarithm transformation of MOI, early start of Grade III response, and dengue incidence in Model 3.

Variable	RR	(95% CI)
log (MOI)	1.36	(1.01–1.84)
Early start of Grade III response	0.68	(0.52–0.90)

Abbreviations: RR, relative risk; 95% CI, 95% confidence interval; log(MOI), logarithm transformation of mosquito ovitrap index.
