	HLC location*	SR (mean ± SD)†	Placebo (mean ± SD)	% Change (95% CI) SR vs. placebo	Two-sided P-value
Parous	Indoor (n = 5,784)	0.41 ± 0.44 (n = 2,537)	0.41 ± 0.45 (n = 3,247)	−10.2 (−62.1, 113.2)	0.808

^*Position of collect/or conducting human-landing catch (HLC) (indoor = near center of house; outdoor = on house verandah ∼1 m from the edge of exterior wall).

^†Mean and SD are descriptive statistics, and % change was obtained from fitting negative binomial models.
