^*Only the most relevant variables are shown, with domestic, peridomestic, and sylvatic variables defined in the study as dependent. “Vector sightings inside the house” and the most recent vector sighting had five categories: < 1 day, < 3 days, < 1 week, < 1 month, and > 1 month. The significant variables are highlighted. P values are in the top portion of the boxes. Boxes without OR represent squares without a value.

OR = odds ratio; CI = confidence interval; – = no value.
